Hi Anderson
Thanks. I was using a small n for script-testing purposes. I re-ran the analysis with 500 permutations, but produce similar errors (though I was hopeful :( ). My command and feedback are pasted below.
Earlier you tested this same data (sample size=192) earlier without problems on your system. But, something changed in my data somehow at some point (reducing my # obs by 2). So, I had to re-run the data separating procedure (HCP Course 2018 | Practical 11: Task fMRI Analyses, Page 421) to get my original 192 obs back.
wb_command -cifti-separate Y192.dtseries.nii COLUMN -volume-all Y192_subcortical.nii -label Y192_subcortical_label.nii -roi Y192_subcortical_roi.nii -metric CORTEX_LEFT Y192_left.func.gii -roi left.shape.gii -metric CORTEX_RIGHT Y192_right.func.gii -roi right.shape.gii
The PALM analysis for the subcortical file worked as expected after the separating command (above), but I am getting the palm_competitive error for the lateralized cortical analyses (below).
Any suggestions?
Thanks.
Darren
