The cifti-matlab tools, as currently constituted, load the medial wall, whereas the python implementation does not. That is why the two yield a differing number of grayordinates.
The cifti-matlab tools are a bit of a work in progress. If you simply want to load the grayordinates, excluding the medial wall, into matlab you can alternatively use the 'ciftiopen.m' function available here: https://wiki.humanconnectome.org/display/PublicData/HCP+Users+FAQ#HCPUsersF AQ-2.HowdoyougetCIFTIfilesintoMATLAB? cheers, -MH -- Michael Harms, Ph.D. ----------------------------------------------------------- Conte Center for the Neuroscience of Mental Disorders Washington University School of Medicine Department of Psychiatry, Box 8134 660 South Euclid Ave. Tel: 314-747-6173 St. Louis, MO 63110 Email: [email protected] On 6/2/15 9:53 AM, "Donna Dierker" <[email protected]> wrote: Hi Philip, I don't know the python/matlab implementation specifics, but the CIFTI page may be helpful: http://www.nitrc.org/projects/cifti/ The format specification (http://www.nitrc.org/forum/attachment.php?attachid=341&group_id=454&forum_ id=1955) may help.
