Re: [HCP-Users] calculating surface areas

[Glasser, Matthew]

Right I forgot that I can’t just check the dev version… Peace, Matt.

If you just want the surface area of each vertex, -metric-vertex-areas will do this.  If you want the surface area of an ROI, and the ROI is binary (values are zeros and ones), you can do this for a single subject: wb_command -metric-vertex-sum roi.func.gii -integrate surface.surf.gii To get binary rois, you could give a label file to -gifti-all-labels-to-rois, or threshold a metric with -metric-math 'x > 0', or similar. (in the next release, -metric-weighted-stats with the -sum and -area-surface options will also do what -metric-vertex-sum -integrate does) Tim On Sun, Mar 8, 2015 at 3:39 PM, Glasser, Matthew <glass...@wusm.wustl.edu> wrote: Hi Tim, Could you explain how you want users to compute surface areas of ROIs now that the previous command that did that seems deprecated?  The example usage for doing this should probably be in the command’s usage as well, since this will be a common task.   Thanks, Matt.

I have some data from unique populations whose the surface statistics are not summerized in the stat files. Thank you in advance!
