External Email - Use Caution

Hello Freesurfer experts,

I ran the recon-all command and got all the .label files for the segmentations of the cortical areas. However, I have some questions about the label for primary motor and auditory cortex.

I found two types of labels associated with the primary motor cortex: lh.L_M1.label and lh.BA4a_exvivo.label. Are they both valid, and the lh.BA4a_exvivo.label segmentations are finer parcellation than the other one?

I think they came from different techniques, so it's up to you

What's the primary auditory cortex .label file?

We don't have an A1 label as a label file. You can use the transverse temporal in the aparc.annot (heschl's gyrus)

Thanks in advance!
