If you're asking whether we have tools that do myelination-based segmentation from T1, the answer is no. I've found from fMRI that the transversetemporal label does pretty well. doug

Hi Doug, Wow, telepathy…Just resent my email and got this reply. THanks. I need to compute the surface area of primary auditory cortex so was looking for an approach similar to the Hinds V1 approach and came across two papers by your group. So if I can demarcate A1 based on myelination patterns in T1 MPRAGE images from 3T, that will be the best solution. Please let me know if thats possible.

What do you want to do with it? You can extract it out of ?h.aparc.annot or aparc+aseg.mgz, depending on what you want to do with it doug On 03/08/2014 06:48 AM, Ritobrato Datta wrote:
Hi All, I need to demarcate primary auditory cortex in a group of subjects anatomically and I came across the following papers - https://surfer.nmr.mgh.harvard.edu/ftp/articles/2013/2013_-_Wasserthal_et_al... https://surfer.nmr.mgh.harvard.edu/ftp/articles/Sigalovsky_et_al_2006.pdf Is there a script that I can use on my 3T MPRAGE images to get primary auditory cortex ROI ? That will be very helpful. Best, Ri _______________________________________________ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer
