Hello AFNI experts,
I want to double check that I am using the new option of AFNI Clustsim correctly. I have in the past used the version that uses the FWHM and I am surprised by how much different the cluster sizes when using the ACF option.
For example: NN3 2 sided, at pthr 0.05 and alpha 0.05, the original version cluster size is 768 voxels, whereas in ACF version it is 3590. This is

Hi Gang,
How do I attach those files on the message board? It is telling me that the only valid attachments are bmp, gif, jpg, png files... am I missing something here?
Also, if 3dMVM creates an interaction for ALL variables included, then how do I specify a glfCode to do the F-test for Group x Age x Emotion? The 3dMVM help page does not have glfCode examples that include 3 conditions.

Hi Gang,
Thanks. I see that now, I removed emotion from the "bsVars" but I still received the same exact error.
Also, is there a way to specify the within x between interaction in the model, or does it do that automatically?
for example, my main interaction of interest is Group (between ) x Age (between) x Emotion (within).
Is 3dMVM the best program for that, or should I use

Hi AFNI experts,
I am trying to run a 3dMVM for the following model:
Group * Age * Emotion (3 within sub conditions) controlling for motion and sex.
I am getting the error:
"Reading input files: Done!
If the program hangs here for more than, for example, half an hour,
kill the process because the model specification or the GLT coding
is likely inappropriate.
