Hi Attila, the volume in the aseg.stats is partial-volume corrected so they don't have to be the same. cheers, Bruce On Sat, 11 Jul 2009, Krajcsi Attila wrote: Hi, If I want to run a functional ROI according to this: http://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/MultiModalFmriGroup#Gr

Hi Bruce, Yes, mri_info works on all these files, and it states that it's an mgh file and the dimensions look allright and it says: type FLOAT (3). Here's the output for the left hemisphere (with command line) [...@localhost area]$ mri_surf2surf --s fsaverage --sval /home/lmr/subjec

Hi, What does it mean when mris_surf2surf produces the error message that the input file cannot be read "as type 3" ? The file is an .mgh which I converted from an .mgz using mri_convert (mri_convert oldfile.mgz newfile.mgh). I get the same error when I use the .mgz file. Thank yo
