Dear AFNI users-
We are very pleased to announce that the new AFNI Message Board framework is up! Please join us at:

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,

Okay, I can do that, but would the following be the correct coding for the fixed and random effects?
-model "Cond" \
-ranEff '~1+Sib' \
Also, how would I handle another level of nesting (e.g., Condition w/in Sibling w/in Family w/in School)?
Thanks,
Ruskin

Hi, Gang.
I want to use 3dLME to analyze data with family dependencies, similar to Example 6 in Chen et al (2013). However, I can't seem to map the explanation in the paper onto the command syntax of 3dLME.
As a starting point, I just want to replicate a model I can run using lme. The experiment involves 20 subjects organized as 10 families (Fam), each comprised of 2 siblings (Sib), e

Hi, Gang.
I have a question regarding the output for glt tests. Consider the following model and the associated output report for sub-brick 3:
Model:
3dLME -prefix /home/thomaskm_02/huntrh/ESMF_3dLME_TEST/TEST_5/ESMF_3dLME_TEST_5_OUT_1 -jobs 24 \
-model "cond" \
-ranEff '~1' \
-SS_type 3 \
-num_glt 3 \
-gltLabel

Hi, Gang.
Thanks again for the quick reply.
I've re-run my test analysis using FSL Level 1 (individual subject) COPEs as input to 3dLME. One set of COPEs is the output of a emot-fixation contrast. The other set is the output of a shape-fixation contrast.
Unfortunately, I don't think I understand the sub-brick ranges in the 3dLME output.
Here is the model submitted to 3dLM

Hi, Gang.
Thanks for the prompt reply. I have a couple of follow-up questions.
Using sub-bricks 4 and 5 as an example:
-- At sub-brick #4 'emot-shape' datum type is short: -11961 to 32767
[* 0.000223776] -2.67659 to 7.33248
-- At sub-brick #5 'emot-shape Z' datum type is short: -13331 to

Hi, Gang (and others).
I'm an FSL user, but would like to use 3dLME to address some complex statistical models. I've been testing 3dLME, and have a few questions regarding input and output files.
1) What type of data is assumed to be in the input files for 3dLME? Are they beta-weights, and, if so, would the AFNI version of that be analogous to a cope file in FSL?
2) When I re
