From thomas.thesen@med.nyu.edu Thu Jan 6 17:48:52 2011 From: "Thesen, Thomas" To: freesurfer@nmr.mgh.harvard.edu Subject: [Freesurfer] variance or stdev from average Date: Thu, 06 Jan 2011 17:48:48 -0500 Message-ID: MIME-Version: 1.0 Content-Type: multipart/mixed; boundary="===============3123817310121945842==" --===============3123817310121945842== Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: quoted-printable Hi, I am using mris_average_curvature to create an average thickness map across s= ubjects (registered to fsaverage). The command line I am running is: mris_average_curvature lh.thickness lh sphere.reg subj01 subj02 .... subj20 = outputfile This produces the average, but my question is if there a way to also create a= measure of variability at the vertex level from that group, e.g. the associa= ted variance or standard deviation? Thanks, Thomas ------------------------------------------------------------
