Hi experts, I'm back with some more RBA-related questions.
Sample code:
RBA -prefix piper_int -Subj subj -ROI ROI -Y Y \
-PDP 12 1 -chains 4 -iterations 5000 -model '1+neg+pos+group+sex' \
-distROI 'student' -distSubj 'student' -distY 'student' \
-qVars "neg,pos" -cVars "group,sex" -EOI "neg,pos,group,sex" \
-stdz "neg,pos" \
-dataTable int_rba12.txt
Question 1. When looking at the output (e.g., int_rba12.txt), the GLM (for reference only) for both cVars are identical, though the region effects (RBA results) are different. We've looked through the .RData file and can't find anything to indicate why this might be the case and were wondering if you had any insight.

Question 2. In running bayes_view to visualize ridge plots, the GUI only shows one EOI (sex) with no ability to toggle to other EOI views across multiple browsers. I initially thought that -PDP 12 1 was the culprit, but the issue persists even when re-running RBA with -PDP 12 4. I've clicked around and didn't find any other options to toggle. Any ideas on how to fix, or if I'll need to manually create these ridge plots in R?
I'm happy to provide any other code, output, etc. that might be helpful. I look forward to your responses, TIA!
