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 Gang,

I'm very interested in modeling trial as a random factor. Do I understand correctly from the bioRxiv paper that the implementation would be to use 3dREMLfit with one regressor for each trial, and then use 3dLMEr with each trial as an input file for one massive model? As in (following your example):

3dLMEr -prefix LME \
...
Subj Emotion Trial InputFile \
s1 pos T1 s1_decon+tlrc'[1]' \
s1 pos T2 s1_decon+tlrc'[2]' \
s1 pos T3 s1_decon+tlrc'[3]' \
...
s1 neu T1 s1_decon+tlrc'[x]' \
s1 neu T2 s1_decon+tlrc'[y]' \
...
s2 pos T1 s2_decon+tlrc'[1]' ...

Thank you,
nmuncy
