Prapti,
You can use mri_label2label to do that, something like:
mri_label2label --srclabel rh.your_dlpfc.label \ --srcsubject subject_you_drew_label_on \ --trgsubject the_other_subject \ --trglabel rh.your_dlpfc.label \ --regmethod surface \ --hemi rh
so you draw the label on one subject (saved as rh.your_dlpfc.label in this example), and you would do this mri_label2label command for each subject that doesnt have a label. this assumes you've run freesurfer recon-all -all for each subject already, so that each has the sphere.reg file (which is how it does the label mapping).
see also mri_label2label --help.

Dear all,
I am trying to measure the volume of the dorsolateral prefrontal cortex in a large group of subjects. I have created a new label that only includes the dlpfc for a subject but realised that the same label file cannot be used on another subject. Has anyone created a customised ROI for dlpfc to use in a group of large subjects or can point me in the right direction ? The only other option I know is to individually create a label file for each subject which would be very time consuming.
Thanking you in advance,
Prapti
