Dear all,

Apologies for my ignorance.

I’m trying to extract the transverse gyrus, transverse sulcus, planum temporale and temporal pole from the inflated surface created by freesurfer. What I intend to do, is to convert these labels into spm analyze format files in native space, and apply the deformation parameters from DARTEL into standard space.

Until now, I have created new labels for these regions, and using the mri_label2vol command line:

mri_label2vol –label subject/label/label1.label –temp subject/orig.mgz –fillthresh .5 –o label1.bshort

However, it prompted me for a register.dat file and I do not have this. Using the advice from Dr. Doug Greve, I have tried to use the –identity:

mri_label2vol –label subject/label/label1.label –temp subject/orig.mgz –identity –fillthresh .5 –o label1.bshort

When I did this, I get 256 files for label1.

So I think I might have done something wrong here.

Could someone please advise me how to do this? I’m lost here.

Thank you very much in advance!

Best regards,

HweeLing
