Question about using multiple reference RDMs and multiple candidate RDMs for signed-rank test #21

I would like to base my model RDMs on the behavioral data of each subject. I have transformed my behavioral data into individual model RDMs. Now I would like to use these model RDMs (one for each subject) as reference RDM and then RDMs from different ROIs as candidate RDMs. However, when I have multiple reference RDMs, the toolbox then averages multiple instances of any candidate RDM (toolbox command window output: Found 24 instances of the reference RDM. Averaging all instances of each candidate RDM). Is there a way to use the toolbox that it allows multiple reference RDMs AND correspondingly multiple candidate RDMs? Because I would like to test in which of the ROIs the subject specific brain RDMs are most similar to the subject specific model RDM, but also use a signed-rank test to test for statistical inference across all subjects.

Hello @lisadandolo,
I would like to implement a similar analysis using the searchlight procedure in the toolbox, where each participant has their own candidate RDM based on some behavioural criterion. Were you able to do this?
Thank you,
Mrinmayi
