Hi Anupa,

I expect you used:
mri_mergelabels -i lh.G_front_middle.label -i lh.S_front_inf.label -i lh.S_front_middle.label -o your.lh.dlpfc.label 
To create your dlpfc.

If so, you can use:
mris_anatomical_stats -b  -l your.lh.dlpfc.label $i lh>>your.lh.dlpfc.label.txt
#make sure you don't forget right hemi!

In your txt file you'll find all necessary info.
You can use something like (when your cwd is /subject/label/
echo `sed -n '13p' your.lh.dlpfc.label.txt`>>/YOURPATH/lh.dlpfc.merged.table
#make sure you don't forget right hemi!

Here you only extract the necessary info from the textfile for this subject. Don't forget to print the headers (line 12) once on top of your table file.

If you need additional scripts, I can send them to you.

Good luck.
Cédric

Dear All,
 
I went thru the link suggested by Mr. Cedric.https://mail.nmr.mgh.harvard.edu/pipermail/freesurfer/2009-February/009600.html
>From that mail I understood how to create the label for multiple subjects.

I already created a DLPFC for one individual.
I want to know how to measure the corticla volume (mm3) of that created DLPFC.

Any helps'll be greatly appreciated.

Dear Cedric,

Thanks a bunch.
I'll try with mri_label2label.

Dear Anupa,

The DLPFC is not a standard label in FS. So you need to create it yourself by merging the following labels:
DLPFC:  middle frontal gyrus, and inferior and middle frontal sulci

Best,

Dear FreeSurfer Experts,

I'd like to know how to measure the volume of a brain region using freesurfer.
I know to obtain the volumes after runnin recon-all command. But I don't find the brain volume of my interest which is DLPFC.
How can I get the brain volume of my interest.?


Thanks for your response in advance.
