Hi FreeSurfer team, After recon -all, I got some labels. I would like to export FS labels as seed region for tractography in FSL. My ROI is precentral which is 24th region in DKTatlas40. But I have 2 small questions about dong that: 1. Is there any way to extra this region from labels like a2009s or DKTatlas40? 2. I tried using "mri_label2vol —label label/rh.BA1.label —temp /sub_1_t1.nii —identity —o BA1_in_vol.nii” to study the mri_label2vol script, but my result is very inaccuracy. My T1 image is in 1*1*1 mm³ and FOV is 256*256*158 mm. My results is in attachment，and I really don’t know what’s wrong with it. And could you tell me how to do that in a right way. I would appreciate if you could help me!

Sincerely， Jinnan Best wishes for you!
