Hi,

I am trying to extract the label for the calcarine sulcus from the annotation file. I would actually like to extract it from the aparc+aseg.mgz file, but when I use mri_extract_label, it creates an empty volume. Does this mean that it is not labeled in my volume?

However, I found the label in the annot file, so I am using the command below, but no files output except for my segmentation volume, which causes fslview to crash when I try to load it.

mri_annotation2label --subject fs --hemi rh --labelbase ./rh_annot --seg rh_annot.nii.gz --annotation aparc.a2009s --sd .

Do you have any suggestions?

Also, I would like to project the region 2mm into the white matter, how would I do this?

Thank you!
