Hi Carl,

you can ftp it or filedrop it (both are detailed on the fs wiki site)

Dear Freesurfer Folks,

I have returned to the problem of trying to extract T2 values from a T2-map using aseg & mri_segstats. When I attempt mri_segstats it only returns a small subset of the regions from aseg (see attached file). I would like to attach the T2 map but the file exceeds the 25mb limit for gmail (could I drop the file somewhere?) Could the T2 values need to be in a special format?

Thanks very much for your help.

Carl

Hi Carl, those are all that are in the aseg.mgz. What more did you expect? doug

the corresponding aseg.mgz for this subject (see attached jpegs). Does a tool exist in freesurfer to enable regional sampling of T2 values from the T2-relaxation time map based on aseg?

Thanks for any thoughts.
