I’m new to MVPA and have a question about using MVPA in event-related fMRI data. there are 2 runs, and each run has 80 trials, including 2 conditions in the data. I’m not sure is it enough for using MVPA effectively?
Indeed, this is not a large number of trials. In particular, you probably want to generalize from one run to the other, which leaves few trials to train your model.
