Hi FS experts,
I was wondering what the best way to extract an ROI from an anatomical volume would be. For instance, I would like to create a volume of only the wm-lh-precentral based on the orig.mgz volume and on the segmentation map wmparc.mgz. I know that something similar can be done with the mri_extract_label command, but if I'm not mistaken that command can only be applied to a segmentation volume, and not on an anatomical volume like orig.mgz.
Thanks in advance, Panos
