3dNetCorr - Whole-Brain Maps

AFNI Message Board
1

Hello all,

I’m having an issue with 3dNetCorr that I believe might be AFNI version [Precompiled binary linux_openmp_64: Sep 4 2016 (Version AFNI_16.2.16)] and/or machine dependent. Basically, everything appears to have run correctly and without error but the whole-brain (i.e. WB_Z_ROI_XXX.nii) maps are “empty” and approximately 2KB in size. It’s particularly confusing because the other files, including the .netcc file, look normal.

Thoughts?

Thanks,
-Andy

Hmm, there was a dark period in 3dNetCorr’s history where it returned all 0s for the Z-score WB maps. From the history:
https://afni.nimh.nih.gov/pub/dist/doc/program_help/history_all.html
this was fixed in November:

    Z-score WB maps were all zeros-> now have values.

    Hopefully even the correct Z-values.

I’m pretty sure that that would be the cause of this badness. So, probably the best bet would be to update your AFNI version, and let me know what happens?
