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.
>Well, if you want to threshold for the t-statistic with its upper tail, use step(a-a_threshold); for the lower tail, use step(a_threshold-a); and for the two-tailed case, use step(abs(a)-a_threshold).
OK, but suppose I had adopted a_threshold in the AFNI viewer to have a p < 0.01, if i only consider its upper tail the p value associated with those voxels will be 0.005, right?
