Subject: Re: [HCP-Users] calculating surface areas
It is not deprecated in the current release. In the next release
-metric-vertex-sum will be deprecated by -metric-stats and
-metric-weighted-stats. The -metric-vertex-sum command will still work for
several releases, but the new commands are more flexible, and will be the
recommended commands to use in new scripts.
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)

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.

Subject: [HCP-Users] calculating surface areas
Hi, HCP experts
Could someone tell me what is the best way to calculate the surface areas of
the white and gray matter in Workbench? I have some data from unique
populations whose the surface statistics are not summerized in the stat files.
Thank you in advance!
Longchuan
