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

Hi all,

We're experimenting with the new PTA program and after getting it to run successfully have a few questions...
Following Example 3, our model goes something like this:
PTA -prefix def2_pta \
-input PTA.txt \
-model 's(def2,k=6)+s(def2,by=MvF,k=6)' \
-Y 'avgCBF' \
-prediction pred.txt \
-verb 1

Everything runs and we seem to have some significant results, however, the entire prediction and SE columns are NA. I've tried a few different iterations to see if there was something wrong with our model or if we needed additional flags, but I'm stumped...any suggestions?

Running AFNI: Precompiled binary linux_ubuntu_16_64: Mar 17 2021 (Version AFNI_21.0.20 'Titus') with R 3.6.0
