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

There is a slightly complex way. Suppose you have a collection of 3D+time datasets that you want to 3dTcat together, then 3dDeconvolve-ize. The problem is that the intermediate 3dTcat-ed dataset is too big. The solution I can offer you is

(a) Use 3dZcutup to cut a 1 slice dataset out of the each of the input 3D+time datasets.

(b) 3dTcat these 1 slice+time datasets together

(c) Analyze the resulting long 1 slice+time dataset with 3dDeconvolve

(d) Do (a-c) repeatedly for each slice, resulting in N output datasets from 3dDeconvolve (1 for each slice)

(e) When done, use 3dZcat to put the 1 slice 3dDeconvolve buckets back together into a glorious 3D bucket dataset with all your results.


If you need help writing a script to do this, post a message. -- bob cox
