Thanks, Ziad.
I've uploaded the data to nimh. The files are:
anat+orig.* -> orig mri
ortho+orig.* -> ortho transformed mri
anat2ortho.mfile -> the file used to transform anat to ortho, which can also used to transform ortho back to anat
FIOLCEKQ_Slmywin_PicReal+orig.* -> the functional data (MEG), with the same coordinate as ortho
FIOLCEKQ_SurfVol+orig.* -> SUMA with freesurfer
talairach.xfm -> the transform file in freesurfer subdirectory.
My purpose is to load FIOLCEKQ_Slmywin_PicReal+orig.* to SUMA. I thought it could be done like: ortho -> anat -> SUMA/FS. Now I am able to do the first step but don't know how to do the second step.
Thanks again,
Chunmao
