Hi all,
We have ROIs (defined in mrVista) that we converted to label files and would like to now make an average ROI. Does a pipeline exist that will help us create an average ROI composed of these label files. We were thinking of using mri_label2label to register the ROIs to a common surface but we unsure how to average the ROIs at that point.
Thank You, Miggy
Hi Miggy
Are the ROIs on different subjects? Do you have surfaces reconstructed for each of them? cheers Bruce

Hi Bruce,
The ROIs all on different subjects, but we've been able to put them all onto an average surface that we made using make_average_surface (using mri_label2label as explained in my previous email). We were hoping that now that they're all on a common average subject that we could some how make one group average ROI with these labels.
Thanks, Miggy

I would convert them to a binary mask (0,1) then average the masks together. Each vertex would then be the "probability" that a given vertex was in the ROI. You can convert the label to a binary mask with a second call to mri_label2label (--outmask option) doug
