Hi Nick,

Would it be possible to send us the surface file and the merged gift file so we can take a look?

Best, Ruopeng

Hello Freesurfer experts,

I recently upgraded to Freesurfer 7.1. Many nice changes so thanks for that.

I often work with merged gifti files and the previous stable version of Freesurfer/Freeview (6.0) had no issue with them. Now, Freeview can view my unmerged overlays but not the merged ones. I get this error:

Number of vertices in overlay data (1 or 1) does not match with surface (327684).

The (very simple) matlab code used for merging giftis is here: https://github.com/viscog-cmu/bids_gen/blob/master/merge_fs_hemi_overlays.m . It simply concatenates left and right overlays into a single one which i plot on a merged surface.

Wondering if anybody has any ideas? I have confirmed on an identical system using all the same files that this issue is specific to Freesurfer 7. The merged overlays work fine in python, matlab, etc.

thanks, Nick
