I just realized that my question was motivated by a misunderstanding of our pre-processessing pipeline. Feel free to get rid of this post.

Hi AFNI folks,
I'm trying to transform the reference frame of the estimated movement parameters. Ideally, rather than having a time course of motion parameters measured relative to, for instance, the coordinate system defined by the middle volume of a functional times series, I would have a time course of motion expressed in a reference frame shared by all subjects, perhaps the native sca

Hi Gang Chen,
Thanks yet again for the quick response. I'm not sure how I missed the fact the the Age factor was absent. In any event, my basic question about the syntax still remains.
Generally what I'm interested in doing is examing the model predicted time courses at different combinations of predictor values.
Let's say I used the more intricate model with the Time*Age in

Hi AFNI Folks,
I have a question about 3dLME's glt syntax. For this analysis I have extracted an average HRF with 20 time points from many subjects, some of whom have multiple measurements. For each subject we calculated the a metric of motion, over the course of all of the trials that contributed to the estimate of the HRF. This measure and its square are referred to as 'TrialDispla

Hi Gang Chen,
Thanks for the quick reply. I had just figured that out and was about to update my post. I do have another question about 3dLME's glt syntax, but I'll start another thread for it.
Cheers!

Dear AFNI Folks,
I've run into some trouble using 3dLME and referencing a separate dataTable file. Perhaps you'd be good enough to point out the error of my ways.
The following command works for me:
#!/bin/bash
3dLME \
-prefix LELMLeftLME \
-model "1+Time" \
-ranEff '~1' \
-dataTable \
Subj Time InputFile \
