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.
Looks like you are on the cusp of runability: you need 9 time points.
I am not sure what correlation values of so few time points would mean. The stdev of a Pearson correlation value scales with 1/\sqrt(N-2), so for N=8, that would be 1/sqrt(6) ~ 0.4, which is preeeettty huge, consideration the Pearson r range is [-1, 1]. That means that your estimates with so few time points would be dominated by noise.
