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

Hmm. In calc_shift() I found this:
/*----- enter and sort array of differences -----*/
for (i = 0; i < m; i++)
for (j = 0; j < n; j++)
node_addvalue (&head, yarray[j] - xarray);

which is done once per voxel. So that's certainly going to take some time.

We sometimes use Ns and Ms of over 100, too, and we need to raise MAX_OBSERVATIONS to do that. Maybe the default could be set to 300?
