Hi freesurfers, I am interested in studying the difference between the outer and deep white matter volume in my study groups. I am thinking in the following procedures: 1. If there is any way in Freesurfer to do segmentation for the white matter (only in the depth of 3 cm) starting from the

Hi Lena Sure, but you will need to run all your subjects through recon-all first. The if the ROI is in MNI space you can use mri_label2label to map it to our group space fsaverage. Cheers Bruce > On Sep 4, 2015, at 9:27 AM, Lim, Lena wrote: > > Sorry, I haven’t heard any

Thanks, Bruce. I ran the recon-all for all subjects before and then did the group analysis using the mri-glmfit command and qdec. Sorry, I don’t quite understand. What exact command do I use? Mri_label2label --srcsubject fsaverage --srclabel fsaverage/label/(spm roi image file names?)

Hi David I don't think there's an easy way to do it all at once unless you apply the transform to the orig.mgz then rerun recon-all (which will not be the same as applying it to the outputs) sorry Bruce On Fri, 4 Sep 2015, David Grayson wrote: Hi all,   I would like to take a single
