I'm trying to do RSA on source space data in a searchlight analysis. I've done source reconstruction and scout definition. My problem right now is I don't know how to extract the source space values of the scout that I created.
I don't want to downsample the source space because that would lead to loss of specificity. The scout I created contains 30 voxels, and the data I hope to get after extraction is 30 rows * 300 time stamps.
Thank you so much!
