Dear all-

 

Today I tried mkbrainmask-sess (first time), and got the error message shown below:

The input data (fmcss) were motion-corrected, spatial-smoothed, and intensity-normalized using fsfast (the newest version released). Could anyone tell me how to fix this problem? Thanks for your help!
