Aggregating multiple runs when using PyMVPA

Hi everyone,

I am using the BIDS PyMVPA app (https://github.com/BIDS-Apps/PyMVPA) on an fMRI dataset containing three runs. There are multiple conditions within each run. I would like to aggregate the three runs and classify conditions across the runs. What is the best way to aggregate these runs and deal with the new time points?

Thank you,
Amanda
