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 Janeen,

I cannot think of a way to do that, not in the renderer itself.
However, that would not be so hard to do with some external
drawing program, such as GIMP, which comes with Linux. By
"selecting contiguous regions", you should be able to separate
the background, and change it to white.

The renderer does not have any controls over what to display as
"background" values. And even if you store a list of those
images via "accumulate", the controls to alter the brightness,
colors, etc. do not affect them.

Sorry,

- rick
