Dear FS,

after running retinotopy analysis over different subjects i d like now to compare the impact of the activation among the different areas among the subjects. The information to analyse is to find in ..user/bold/retinotopy/fieldsign, the file structure used by Freesurfer. My question is after loading the different fieldsign-?h files and reading them in matlab i got vectors of different length which is the number of the vertices containings values -1,0,1...so far so good, now i wanted to konw how to register those vertices so i can have a common base for a comparison between the different files of the different subjects.

I hope someone could help

Cheers

Dave
