+Emperor 0.9.3
+=============
+
+* `Use gradient colors` checkbox is now found under the `Colors` tab.
+* Merge the `Options` and `View` tabs; additionally the global opacity slider and global scale slider were moved to their respective tabs.
+* `Use gradient colors` checkbox now uses the standard blue -> red color gradient
+* Add Emperor to the Python Package Index, now you can install Emperor running `pip install emperor`.
+* Remove dependency on QIIME and PyCogent.
+* Emperor now depends on qcli and Numpy.
+
+*Bug Fixes*
+
+* Add more meaningful error message for biplots when the contingency table passed included only one row.
+
+Emperor 0.9.2 (24 Oct 2013)
+===========================
+
+*Bug Fixes*
+
+* Fixes bug where files named `procrustes_results.txt` would not be ignored in a plot comparison.
+
+
+Emperor 0.9.1 (21 Oct 2013)
+===========================
+
+*New features*
+
+* Scientific notation is now taken into account in the GUI for scientific coloring.
+* GUI is usable in mobile devices that support WebGL.
+* User documentation: tutorial, installation instructions, GUI description, etc.
+* Ability to make plot comparisons (very useful for procrustes analysis plots).
+* The user can select the number of axes to be considered in the GUI and re-plot using lower axes; this is, for example: PC3 vs PC4 vs PC10.
+* In missing_custom_axes_values you can reference other column within the mapping file to place the samples without numeric values at different points in the gradient.
+* Parallel plots functionality.
+* Separated out some options to the View menu.
+* The "Colors" tab now has a selector, which allows to use the arrows to move between categories.
+* Default coloring scheme is discrete.
+* Add color pickers for the axes and axes labels.
+* To take a screenshot (PNG) of your current visualization you can press `ctrl+p`.
+* Export to SVG your visualization.
+* Emperor now relies on QIIME 1.7.0.
+* Added option `--number_of_segments` to control the quality of all spheres
+* Labels for biplots now have a color picker.
+* Add color pickers for connecting bars in coordinate comparison plots.
+* Add option to select a master set of coordinates when making a comparison plot.
+* Adds a feature to negate axes. With this feature you can negate the coordinates of each data point. As a result, the spheres and/or edges will be adjusted appropriately.
+* Minor additions to the separator controller for the side bar.
+* As of 308629f550ff3e108903d3bcf1ce76ce85f4cb96 Emperor is now released under a BSD license.
+
+
+*Bug Fixes*
+
+* Fixes recenter camera not working.
+* Category names are sorted alphabetically.
+* Category names with non-alphanumeric characters are colored correctly now.
+* Biplots checkbox now accurately reflects status of biplot visiblity rather than opposite.
+* Comparison bars checkbox now accurately reflects status of the visiblity rather than opposite.
+* Scaling by percent explained now works with vectors and coordinate comparison plots.
+* Fixed bug where only the first bars in coordinate comparison plots could be hidden.
+* Improved documentation for saving and exporting images.
+* Emperor now fails graciously when WebGL is not enabled and gives you a few suggestions on how to get it to work.
+
+
+
+Emperor 0.9.0 (14 May 2013)
+===========================
+
+*New features*:
+
+* Intuitive and modern graphical user interface.
+* Simple workflow to modify the color of a sample/label from the user interface.
+* Color the labels for the samples by a category in the mapping file.
+* Scale the elements in the plot by the percentage explained from the user interface.
+* Notify the user when values will be removed from the input files.
+* Search for a sample name from the graphical user interface.
+* Show a selector in the plot when double-clicking a sample name.
+* Show and hide samples by a category in the mapping file.
+* Change the opacity of spheres/ellipses from the graphical user interface.
+* Change the size of a sphere from the graphical user interface.
+* Biplots can be created with a custom axis.
+* The color of the biplot spheres can now be changed from the user interface.
+* Extensive script usage testing
+* Addition of contextualized error messages.
+* Reduced output size for datasets with rich mapping files.
+
+*Performance improvements*:
+
+* Improved performance and responsiveness from the graphical user interface.
+* Superior graphics quality; elements are rendered in the graphics card not in the CPU.
+* Enhanced performance to create the output files.

+Emperor Installation Notes
+==========================
+
+Emperor is a python package that relies in [QIIME](http://www.qiime.org), [NumPy](http://www.numpy.org) and [PyCogent](http://www.pycogent.org). These packages must be installed prior running the `setup.py` script.
+
+To download Emperor, use [this link](https://github.com/qiime/emperor/archive/master.zip) or use git to get the latest version of the repository:
+
+ git clone git://github.com/qiime/emperor.git
+
+Installation
+============
+
+To perform a global installation of Emperor, execute the following command from a terminal session:
+
+ python setup.py install
+
+If you do not want to do a global installation, you will have to add the Emperor scripts and libraries to the `PATH` and `PYTHONPATH` environment variables. To add these variables to your `.bash_profile` issue the following terminal commands:
+
+``` bash
+echo "export PATH=$HOME/emperor_bin/:$PATH" >> ~/.bash_profile
+echo "export PYTHONPATH=$HOME/emperor_lib/:$PYTHONPATH" >> ~/.bash_profile
+python setup.py install --install-scripts=~/emperor_bin/ --install-purelib=~/emperor_lib/ --install-lib=~/emperor_lib/
+```
+
+To test for a correct installation, open a new terminal window and issue the following command to see the help of `make_emperor.py`:
+
+ make_emperor.py -h

+Emperor
+=======
+
+[](https://travis-ci.org/qiime/emperor)
+
+Emperor is a next-generation tool for the analysis and visualization of large microbial ecology datasets; amongst many features Emperor provides a modern user interface that will rapidly adjust to your daily workflow.
+
+To start using Emperor, please refer to the [installation notes](INSTALL.md).
+
+## Usage examples
+
+The main interface to create Emperor visualizations is the `make_emperor.py` script, inputing a mapping file and a PCoA data file, will generate an Emperor graphical user interface to analyze and visualize your data.
+
+If you have a QIIME compliant mapping file and a PCoA file, try the following command from a terminal session:
+
+```bash
+make_emperor.py -i unweighted_unifrac_pc.txt -m mapping_file.txt
+```
+
+That command will create a new directory called emperor, there you will find a file called `index.html` open it with Google Chrome to start visualizing and interacting with your data.
+
+Similarly if you have a study expressed over a gradient, for example a study where you have multiple samples over time, you can use this metadata with your visualization using the `-a` option:
+
+```bash
+make_emperor.py -i unweighted_unifrac_pc_time.txt -m mapping_with_time.txt -a TIMEPOINT
+```
+
+Some build examples are bundled with every Emperor repository, you can begin exploring some sample data using **Google Chrome**:

+ <h2>Overview</h2>
+ <p class="lead" align="justify">
+ Emperor is a local full-browser enabled scatter plots visual tool. Its modern user interface, allows you to customize the appearance of your plot by controlling things like: opacity, sphere scaling, coloring, dimensions being presented among many others.
+ <br><br>
+ This document tries to go through an overview of the controls that can be found in the graphical user interface as well as some of the common use cases that Emperor allows you to work with.
+ <br><br>
+ Emperor's graphical user interface is mainly composed of a visualization canvas (left side) and a set of settings controllers (right side). Figure 1 highlights the (a) total number of points being displayed; (b) main display with the first three dimensions of this dataset; (c) tool-tabs to manipulate features of the plot; (d) visualization type selector to switch between parallel plots and three dimensional plots. Figure 2 presents the same dataset but using a parallel plot display.

+ Figure 1. Emperor’s graphical user interface. (a) Sample counter; shows the total number of samples in the dataset and the number of samples that are currently visible. (b) Canvas; main plot scene where the data is displayed. (c) Tool tabs; controls that allow you to modify and interact with your data.

+ <hr>
+ <h2>Description</h2>
+ <p class="lead" align="justify">
+ Emperor presents multiple tabs on the right sidebar, each of these tabs perform different tasks over the data presented in the visualization canvas.
+ </p>
+ <h3 class="muted">Key</h3>
+ <p class="lead" align="justify">
+ Shows a list of the sample identifiers that are contained in the current dataset and a box with the color that the sample is currently colored by on screen. Double-clicking each square, will make an indicator, white arrow, appear on screen.
+ </p>
+ <p align="center"><img src="img/key_menu.png" alt="Key Menu Example"></p>
+ <h3 class="muted">Color</h3>
+ <p class="lead" align="justify">
+ Shows a list of the categories listed under the mapping file column selected in the menu of this tab (for this example DOB). Each category has a color box where you can modify the current color of the samples that belong to this category.
+ </p>
+ <p align="center"><img src="img/colors_menu.png" alt="Coloring Menu Example"></p>
+ <h3 class="muted">Vsibility</h3>
+ <p class="lead" align="justify">
+ Shows a list of the categories listed under the mapping file column selected in the menu of this tab, for each of these categories a checkbox and a slider is presented. The checkbox will allow you to hide (unchecked) or show (checked) samples that belong to each category. The slider controls the opacity of the samples defined under this category.
+ </p>
+ <p align="center"><img src="img/visibility_menu.png" alt="Visibility Menu Example"></p>
+ <h3 class="muted">Scaling</h3>
+ <p class="lead" align="justify">
+ Similar to visibility but controls the scale of the spheres. The values range from 0.2 to 4, when the slider is located at a value of 2, the spheres will be twice as bigger as in the beginning. By default all sliders are set to a value of 1.
+ </p>
+ <p align="center"><img src="img/scaling_menu.png" alt="Scaling Menu Example"></p>
+ <h3 class="muted">Labels</h3>
+ <p class="lead" align="justify">
+ Similar to Visibility but controls the appearance of the labels. The checkbox at the top of this tab will add or remove the labels from the plot.
+ </p>
+ <p align="center"><img src="img/labels_menu.png" alt="Labels Menu Example"></p>
+ <h3 class="muted">Axes</h3>
+ <p class="lead" align="justify">
+ Although Emperor is only capable of displaying three dimensions at a time, the dimensions that are being displayed can be selected from this menu. To update the plot to reflect the latest changes, you’ll have to click the refresh button.
+ </p>
+ <p align="center"><img src="img/axes_menu.png" alt="Axes Menu Example"></p>
+ <h3 class="muted">View</h3>
+ <p class="lead" align="justify">
+ General features of a plot as presented by Emperor, are modified from this menu; by default Emperor will try to color samples along a continuous color gradient, to turn this option off, select “Use discrete colors”. The sphere opacity and sphere scale controls override the options in Scaling and Visibility tabs.
+ </p>
+ <p align="center"><img src="img/view_menu.png" alt="Options Menu Example"></p>
+ <h3 class="muted">Options</h3>
+ <p class="lead" align="justify">
+ The different options that will affect the overall plot as it is are listed under this tab. Scaling the coordinates by the percent explained, will re-scale the data by multiplying all the values in that dimension by the ratio explained. By default, Emperor will color the samples in a discrete way, each group is independent, but you can select “Use gradient colors” to create a gradient in the values of the columns. This is helpful when we are trying to display categories that [...]

+ To perform a global installation of Emperor, execute the following command from a terminal session:
+ <br>
+ <pre><code>python setup.py install</code></pre>
+ </p>
+ <p class="lead" align="justify">
+ <br>
+ If you do not want to do a global installation, you will have to add the Emperor scripts and libraries to the <code>PATH</code> and <code>PYTHONPATH</code> environment variables. To add these variables to your <code>.bash_profile</code> issue the following terminal commands:
+ <br>
+ <pre><code>echo "export PATH=$HOME/emperor_bin/:$PATH" >> ~/.bash_profile<br>echo "export PYTHONPATH=$HOME/emperor_lib/:$PYTHONPATH" >> ~/.bash_profile<br>python setup.py install --install-scripts=~/emperor_bin/ --install-purelib=~/emperor_lib/ --install-lib=~/emperor_lib/</code></pre>

+ <h2>Tutorial</h2>
+ <h3 class="muted">Introduction</h3>
+ <p class="lead" align="justify">
+ This tutorial attempts to cover most of the common use cases within Emperor.
+ <br>
+ The dataset that we will use to exemplify Emperor’s functionality, comes from the <a href="http://www.pnas.org/content/107/14/6477.long">Fierer et. al. 2010</a> article, where three individuals and their keyboards were sampled, Figure 1.
+ <br>
+ To get started, first download and unzip these <a href="files/files.zip">files</a>, here you will find a principal coordinates file, and a mapping file. These input files are in the standard format used in <a href="http://www.qiime.org">QIIME</a>. Before continuing with the tutorial make sure you have the latest version of <a href=" https://www.google.com/intl/en/chrome/browser/">Google Chrome</a> installed in your computer. The sections described in this tutorial are:
+ <br>
+ <ul >
+ <li><a class="lead" href="#section0">Command Line Interface</a></li>
+ <li><a class="lead" href="#section1">Graphical User Interface</a></li>
+ <li><a class="lead" href="#section2">Changing The Coloring</a></li>
+ <li><a class="lead" href="#section3">Changing The Opacity</a></li>
+ <li><a class="lead" href="#section4">Color Schemes</a></li>
+ <li><a class="lead" href="#section5">Exporting</a></li>
+ <li><a class="lead" href="#section6">Sharing</a></li>
+ </ul>
+ </p>
+ <hr>
+ <h3 class="muted" id="section0">Command Line Interface</h3>
+ <p class="lead" align="justify">
+ Emperor offers a convenient command line interface script (<code>make_emperor.py</code>), see the <a href="installation_index.html">installation notes</a> for further details. The minimum inputs that this interface requires are a coordinates file and a mapping file, it’s worth noting that the script interface offers many options that allow the user to refine the amount of data to visualize or even to change the way it will be presented, calling <code>make_emperor.py -h</code> [...]
+ <br>
+ Besides the coordinates and mapping file options, we will also use the <code>-b</code> option and the <code>-o</code> option. The <code>-b</code> option allows us to specify the categories that we want displayed in the GUI, it also allows us to combine columns from the mapping file into a single column. The <code>-o</code> option allows us to specify the name of the output directory.
+ </p>
+ <pre><code>make_emperor.py -i unweighted_unifrac_pc.txt -m mapping_file.txt -b "AGE,HAND,HAND_KEY,BODY_SITE,HOST_SUBJECT_ID,HAND,HAND&&HOST_SUBJECT_ID" -o keyboard</code></pre>
+ <br>
+ <p class="lead" align="justify">
+ Note: when <code>&&</code> is used with the <code>-b</code> option, two categories from the mapping file will be combined, in this case the values in <code>HAND</code> and the values in <code>HOST_SUBJECT_ID</code> will be concatenated.
+ <br>
+ A new folder named keyboard will be created, as this is the name we gave via <code>-o</code>, here you will find two files, these two files will be named the same for all datasets:
+ </p>
+ <p class="lead" align="justify">
+ <ul>
+ <li><code>index.html</code></li>
+ <li><code>emperor_required_resources/</code></li>
+ </ul>
+ </p>
+ <p class="lead" align="justify">
+ <br>
+ Opening <code>index.html</code> with Google Chrome will present the main GUI, to do so you can right click this file and make sure you open it with Google Chrome.
+ </p>
+ <hr>
+ <h3 class="muted" id="section1">Graphical User Interface</h3>
+ <p class="lead" align="justify">
+ Once you open the <code>index.html</code> file that was just generated, you should see something similar to the following figure:
+ </p>
+ <p align="center"><img src="img/tutorial/1.png" alt="GUI 1"></p>
+ <p class="lead" align="justify">
+ For a detailed explanation of the options available from the main interface refer to the <a href="description_index.html">description section</a>.
+ <br>
+ </p>
+ <h3 class="muted" id="section2">Changing The Coloring</h3>
+ <p class="lead" align="justify">
+ Spheres drawn in the main canvas are colored by the selected column in the mapping file under the Colors tab, in this example <code>AGE</code>. The available metadata categories are sorted in alphabetical order hence <code>AGE</code> is the first in this list. To change the coloring scheme click the Colors tab, then in the dropdown menu shown at the top click to select <code>HOST_SUBJECT_ID</code>. Now that samples are colored by this grouping, spheres will be colored in thre [...]
+ </p>
+ <p align="center"><img src="img/tutorial/2.png" alt="HOST_SUBJECT_ID Coloring"></p>
+ <p class="lead" align="justify">
+ Modifying the colors used to distinguish between subjects is achieved by clicking the frame by the side of each subject name. For example to change the color of the samples belonging to <code>232:M9</code>, click on the green square by the left side of this label (1), a color picker will appear on screen (2), select a new color by pointing and clicking at it with the mouse; to confirm this selection use the <code>choose</code> button (3).
+ </p>
+ <p align="center"><img src="img/tutorial/capture_2.png" alt="Three panels"></p>
+ <h3 class="muted" id="section3">Changing The Opacity</h3>
+ <p class="lead" align="justify">
+ Similarly to the coloring of the samples, opacity is an attribute that can be determined on a per-category basis. To illustrate an example where this is useful, let’s reduce the opacity in the samples without an <code>AGE</code> value i. e. the keys of the subject’s keyboard. Begin by navigating to the visibility tab and with the slider under the label that reads <code>NA</code>, move it until you reach almost half the opacity. The end result will be similar to the next figure.
+ </p>
+ <p align="center"><img src="img/tutorial/6.png" alt="Opacity reduction"></p>
+ <h3 class="muted" id="section4">Color Schemes</h3>
+ <p class="lead" align="justify">
+ Frequently you will find that metadata categories have multiple values that are easier to visualize with a color map, on the other side when the values have no sequential relationship, it’s better to use what’s called a discrete set of colors. In this dataset the <code>HAND&&HOST_SUBJECT_ID</code> category that we create with the <code>–b</code> option is a good example. Switch to the Colors tab and then in the dropdown menu to change the category from <code>HOST_SUBJECT_ID</ [...]
+ </p>
+ <p align="center"><img src="img/tutorial/treta.png" alt="To Discrete"></p>
+ <p class="lead" align="justify">
+ Pointing out the location of a sample within the plot, can be achieved by using the Key menu for example let’s indicate where is sample <code>M9Indr217.140998</code>. In the Key tab and search for the name either using the text entry box or navigating through the list of values. Once you’ve found it click in the colored square by it’s side and a white arrow will appear on the plot pointing at the place where the sample is located.
+ </p>
+ <p align="center"><img src="img/tutorial/10.png" alt="Filter"></p>
+ <p class="lead" align="justify">
+ Often times PCoA data will span over more than three dimensions, other dimensions can be visualized using the axes menu; just select the three coordinate axes that you want your data to be shaped by and hit the refresh button. In this instance let’s go to the Axes menu select P3 in the Axis 1 drop down menu, P4 in the Axis 2 drop down menu and P5 in the Axis 3 drop down menu, lastly click the refresh button this will redraw the visualization using the coordinate values in eac [...]
+ </p>
+ <p align="center"><img src="img/tutorial/exes.png" alt="Filter"></p>
+ <p class="lead" align="justify">
+ Dragging the plot with the left button of the mouse, will let you rotate the plot in the direction that the mouse is being moved. If the right click is pressed instead, the plot will be dragged with all it’s elements. To zoom-in or zoom-out in the plot use the scroll wheel. And note that at any time you can go back to the options tab and click recenter camera to go back to the original position.
+ </p>
+ <p align="center"><img src="img/tutorial/rotating_1.png" alt="Filter"></p>
+ <p align="center"><img src="img/tutorial/rotating_2.png" alt="Filter"></p>
+ <h3 class="muted" id="section5">Exporting</h3>
+ <p class="lead" align="justify">
+ Emperor generates publication quality figures in scalable vector graphics (SVG) format. The "Save as SVG" button is found under the "Options" tab, note that if you mark the "Create labels?" checkbox an additional file with legends describing the coloring scheme, a color to category name pair, will be downloaded to your computer.
+ </p>
+ <p align="center"><img src="img/tutorial/11.png" alt="Export Screenshot"></p>
+ <p class="lead" align="justify">
+ In this example setting the file name as "figure_example" renames the legends file as "figure_example_labels.svg" and the current view in the visualization canvas as "figure_example.svg".
+ <br><br>
+ Converting these figures into other formats can be achieved using external and freely available tools like <a href="http://inkscape.org">Inkscape</a>, which conveniently provides a command line utility to convert files into different formats. The following command line call will convert our SVG formatted file to a PDF formatted file.
+ </p>
+ <pre><code>inkscape -f figure_example.svg -A figure_example.pdf</code></pre>
+ <p class="lead" align="justify">
+ More information about the usage of this command line utility can be found <a href="http://inkscape.org/doc/inkscape-man.html">here</a>.
+ </p>
+ <h3 class="muted" id="section6">Sharing</h3>
+ <p class="lead" align="justify">
+ Simply compress the output directory (specified by the <code>-o</code> option in <code>make_emperor.py</code>) and share. The newly created <code>index.html</code> file contained within the output directory can then be visualized and manipulated through the Chrome web browser as long as it is accompanied by the <code>emperor_required_resources</code> folder.
