[Mne_analysis] question about mne_read_morph_map

[Gustavo Sudre]

Hello,

When I read the morph map between subjects A and B, it often happens that the number of vertices in the morphing matrix does not align properly with the number of vertices in the subject's surface file. For example:

[left,right] = mne_read_morph_map('A','B');
and then 
[verts,tri] = mne_read_surface('A_surface-lh.white');

In some cases the length(verts) disagrees with the second dimension of left by a few vertices. When that happens, the second dimension is always smaller (from what I could tell). In such cases, should I just assume the transformation works for the first vertices of verts? Or am I missing something here?

Please let me know if you need more details.

Thanks,

Gus
