[Debian-med-packaging] Seeking Advice on 2.7G Package Data

["Steffen Möller"]

Hello,

I think we all agree that such a bunch of data should not become part of the archive. With biomaj and getData we have two tools that can perform the download of those extra gigabytes from your FTP servers. I suggest to employ them for the job.

With all the historical bias of mine, I had prepared such a solution for the autodock package. See 
debian-med/packages/autodocksuite/trunk/debian/autodock-getdata.install
which installs 
debian-med/packages/autodocksuite/trunk/debian/autodock-zinc.getData 

And the latter reads
$ cat debian/autodock-zinc.getData 
print STDERR "Reading autodock-zinc configuration file\n" if $verbose;

# This file is Copyright (C) Steffen Moeller <moeller at debian.org>
# and made availabel under the terms of the GPL version 2 or any
# later version as presented in '/usr/share/common-licenses/GPL-2'.

# No chemical post-processing required since all files are in pdbqt format
# already. But one needs to untar the files.

foreach $n (("asinex", "chembridge_buildingblocks_pdbqt_1000split", "drugbank_nutraceutics",
             "drugbank_smallmol", "fda_approved", "human_metabolome_pdbqt_1000split", "otava",
             "zinc_natural_products")) {

        print "$n\n";

        $toBeMirrored{"zinc.pdbqt.$n"}={
          "name" => "ZINC - PDBQT formatted – $n",
          "tags" => ["pdbqt","compounds"],
          "source" => "wget $sharedWgetOptions http://zinc.docking.org/pdbqt/$n.tar.gz",
          "post-download" => "tar --no-same-owner --exclude prepare_lig.log --exclude mol2 -xzvf $n.tar.gz && chmod -R go+r . && find . -type d -exec chmod +x {} \\; "
        };
}

1;

Olivier, how would one do that for biomaj? 

Many greetings

Steffen
