[Mne_analysis] The problem with saving morphed labels to an annot file

[Peled, Noam]

Hey Alex,

Yes, sure!

You can find the code here:

https://github.com/pelednoam/mmvt/blob/master/src/misc/labels_morphing_problem.py

I'm using the Lausanne125 parcellation (http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0048121), but this problem can also be replicated using the aparc.DKTatlas40 atlas (or almost any other atlas I assume).

If you wish to run it with the Lausanne125 parcellation, the fsaverage annot files can be found here:

Thanks!

Noam

hi Noam,

I personally don't have a solution for this. Maybe someone else?

could you provide a code snippet to replicate the pb?

Alex
