Hi Lee, Bruce is correct in that some ROIs cross two or more lobar boundaries (i.e. fusiform) while others (i.e. cingulate subdivisions) can be considered separately or can be included to follow the 4 lobes. To the best of my ability, if you are using the *h.aparc.annot, you can add up the individual ROIs as such to get the lobes:
Frontal: Superior Frontal Rostral and Caudal Middle Frontal Pars Opercularis, Pars Triangularis, and Pars Orbitalis Lateral and Medial Orbitofrontal Precentral Paracentral Frontal Pole Parietal: Superior Parietal Inferior Parietal Supramarginal Postcentral Precuneus Temporal Superior, Middle, and Inferior Temporal Fusiform Transverse Temporal Entorhinal Temporal Pole Parahippocampal Occipital: Lateral Occipital Lingual Cuneus Cingulate (if want to include in a lobe): Rostral Anterior (Frontal) Caudal Anterior (Frontal) Posterior (Parietal) Isthmus (Parietal) Best, rahul > Hi Bruce, > > Are you saying that you don't think I even could build these lobar groups > using the existing codes in the LUT.txt file? > > Lee > > -----Original Message----- > From: Bruce Fischl [mailto:[EMAIL PROTECTED] > Sent: Saturday, April 14, 2007 2:21 PM > To: [EMAIL PROTECTED] > Cc: [EMAIL PROTECTED] > Subject: Re: [Freesurfer] major lobes - frontal, parietal occipital and > temporal > > Hi Lee, > > sorry, not really - we've never done a lobar parcellation, and I don't > think the existing units break down that way. > > Bruce > On Sat, 14 Apr 2007 > [EMAIL PROTECTED] wrote: > >> I know that I could go thru the >> FreeSurferColorLUT.txt >> file to get codes for different cortical structures. >> Is there an easier way to get the major lobes: >> frontal, parietal occipital and temporal. >> >> Lee >> _______________________________________________ >> Freesurfer mailing list >> [EMAIL PROTECTED] >> https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer >> >> >> > > _______________________________________________ > Freesurfer mailing list > [EMAIL PROTECTED] > https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer > > > _______________________________________________ Freesurfer mailing list [EMAIL PROTECTED] https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer
