3dMVM output

Hi AFNI experts,

I am very new to AFNI and have been muddling my way through code. Now I have (another) very simple question: How do I view 3dMVM output?
My 3dMVM code is shown below. Sbd stands for amygdalar subdivisions, of which I have 6.

3dMVM -prefix output -jobs 10
-bsVars “DTS+IQ+Age+FD+Sex+DiRace”
-wsVars Sbd
-qVars “DTS,IQ,Age,FD”
-mask greymatter.nii
-dataTable
Subj DiRace Sex Age DTS IQ FD Sbd InputFile
…

All the output I received was one Output+tlrc BRIK, one Output+HEAD file and six 1D files (one for each of of my subdivisions). However, all the 1D files were empty. Is this expected? How do I view these output files now?

Are your input files in NIfTI format? If so, consider specifying the output file as

-prefix output.nii

What exactly are those input files?

Yes - input files are .nii

I’ll give re-specifying the output file a shot. Thank you

Example input files are below for one participant (#xxx). Each participant has 6 input files: one file for each amygdala seed. They are zmaps of connectivity between amygdala seed and whole brain.

Do you still get those 1D files in the output?

Sorry for the last response -

using a .nii output worked! I didn’t get those 1D files again.

Thanks!!
