AFNI Message Board

Dear AFNI users-

We are very pleased to announce that the new AFNI Message Board framework is up! Please join us at:

https://discuss.afni.nimh.nih.gov

Existing user accounts have been migrated, so returning users can login by requesting a password reset. New users can create accounts, as well, through a standard account creation process. Please note that these setup emails might initially go to spam folders (esp. for NIH users!), so please check those locations in the beginning.

The current Message Board discussion threads have been migrated to the new framework. The current Message Board will remain visible, but read-only, for a little while.

Sincerely, AFNI HQ

There are at least a few ways to output the coordinates of the nodes of a surface. First, the suma GUI shows them as you right click on the surface, but that gets tedious if you want more than a few. If you want all the coordinates, then try one of these:

SurfaceMetrics -i cubo.gii -coords (the output here, coords.coord.1D.dset, can color the datasets in suma as above using the first column - node index)
or
SurfMeasures -spec ./tmp_suma/cubo.spec -surf_A cubo -out_1D testout.1D -func coord_A
or
Convert the surface to an ascii text format like .asc or .ply, then view the file itself
gifti_tool -infile cubo.gii -write_asc cubo.asc
ConvertSurface -i ./tmp_suma/cubo.ply -o cubo2.asc

The coordinates here either use RAI or LPI coordinate order.
