Hi Nick, That works PERFECTLY! Thank you so much, it has been a big help!
I hope I may ask you another question: I am actually trying to convert each freesurfer-label (from aparc.annot) into separate surfaces (not gifti-labels) So ideally I would convert lh.precentral.label > lh.precentral.gii. I have used the command "label2surf", Part of FSL (build 504). (and I have used the "new" gifti lh.white created with your updated version as the input surface) However, the output gifti does not open in matlab (instead shows the same error message seen before). Now I would guess that whatever changes you made to mris_convert would have to be applied to "label2surf" as well. I have noticed some changes in the gifti files with your new mris_convert command. However, I'm not so familiar with the gifti file structure. Maybe I could ask you to have a look into this? Also, If there is a easier way to achieve my goal any advise is welcome! Again, many thanks for your efforts so far! Bastian.
