I have 16 nifti datasets, one per subject, with each in individual native anatomical space. In trying to get a dataset in the same format as in the hyperlignment tutorial I use fmri_dataset on each individual wholebrain 48 betas and then try to merged then all i.e. <span style="color:rgb(34,34,34);font-family:arial,sans-serif;font-size:13px">ds_merged = vstack((d1, d2, d3, d4, d5, d6, d7, d8, d9, d10, d11, d12, d13, d14, d15,d16)) but this gives the following error pasted at the end,</span></div><div class="gmail_default" style="font-family:garamond,serif;font-size:large;color:rgb(0,0,0)">which I think it is becos the number of voxels is different across subjects.
