Actually, I think the w file only holds one time point, so that prob
wont work. If you want to go the matlab route, you can do something
like:
mri_convert lh.curv lh.curv.mgh # convert to mgh for a template
then in matalb
f = MRIread('lh.curv.mgh');
f will be a struct
f.vol will be a 4d matrix of size 1 x nverices x 1 x 1
Just change f.vol to your data (packing the time dim appropriately),
then
MRIwrite(f,'yourdata.mgh');

sure, if you save it in the right format. The easiest thing to do would be to
save it as a volume, where the 1st spatial dimension is # of vertices on the
surface, and the last (4th one) is the # of time points (the 2nd and 3rd
would both be 1). Or there are other formats you can save in if you like,
include our "w-file" format. I've attached a matlab file for writing it.
cheers,

Hi Bruce:
Is there a way that I can load the MEG timecourse data on the freesurfer
surface? Is it possible that we could get the timecourse waveform for a
specific point on the surface?
Thanks!
