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

Hi Aaron,

CreateIcosahedron can create spherical surfaces quite easily. See -help output for details.

In terms of manipulating coordinates in matlab then writing them back for SUMA's use. You can output surface models in the .1D or the VEC format. Which define a surface with two separate files. A coordinate file, and a triangulation file.
Your best bet is to use ConvertSurface to turn any surface you have into the 1D format and see what it looks like.

Lastly besides loading a surface that you've created into SUMA, you should take a look at the demo scripts: @DriveSuma and @DO.examples

Those scripts run automatically, and illustrate many of the things you want done.

cheers,
ziad
