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

I have saved functional datasets as Intensitiy (subbrick #0) and Correlation coefficient (subbrick #1).

I like to cluster this data (subbrick #0 and #1) using a correlation >0.4 and a cluster rmm = 5.1 and vmul = 140 based on their correlation data (subbrick #1).

The command:
3dmerge -1noneg -1thresh 0.4 -1clust 5.1 140 -1tindex 1 -1dindex 1 -prefix time01clust@1 time01@1+orig

only outputs the clustered correlation subbrick #1. Doing the same with - 1dindex 0 only outputs the intensity subbrick. So I combined those two datasets afterwards to one containing both intensity and correlation, thresholded and clustered by their correlation.

Is there an easier way to achieve that (without taking the detour over the two separate FIM sets)?

Thanks,
Wolfgang
