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 Cesar,

There is nothing wrong with using 1,2,3,4,..., or whatever, for
seeds. Your seed sequence does not need to appear random.
For programs taking a seed, it is common to start with some
modestly large number (e.g. 12345) and just increment from
there.

The main reason programs take seeds is so results can be
reproduced given the same seed, if desired. Some programs
use a fixed seed by default (as 3dkmeans claims to do), some
do not (so repeated calls without a seed would be different).
