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

If you have an 8-bit display, you should have the default visual set to be of PseudoColor type. You can check this by looking at the output of the command "xdpyinfo".

AFNI should still work with PseudoColor displays. However, because there are only 256 "color cells" with such systems. Each program allocates some of these, and AFNI will take a lot of them. The result is that you usually can run only 1 such color hog at a time. Web browsers are big color hogs, so you should quit Netscape (etc.) before trying to run AFNI. Also, if you are on a Linux system, most modern window managers will take ALL the color cells so they can look cool. This makes it impossible to run AFNI. So you want to minimize the color usage of other programs.

A little more info on this subject is in Q#5 in the FAQ list: <[afni.nimh.nih.gov];. However, the best solution is to setup your system to have a visual with greater depth. How to do that is system-dependent.
