The Human Connectome Project (HCP) identified a problem with the version of mris_make_surfaces included with the v5.3.0 distribution of freesurfer. In some instances, the pial surface created in conjunction with provided T2 data was not accurate. However, the 'dev' build of mris_make_surfaces with CVS date 29 Jan 2014 fixes this problem. To help the HCP manage this change, a new tarball bundle of v5.3.0 was created which merely has these changes: - mris_make_surfaces in freesurfer/bin is the updated 'dev' build - the contents of the build-stamp.txt are modified to include the string "-HCP" at the end to differentiate it from the default v5.3.0 - the tarball name itself has the string "-HCP" appended to it This distribution is found here: ftp://surfer.nmr.mgh.harvard.edu/pub/dist/freesurfer/5.3.0-HCP NJS 2Feb2014
