Dear SPM community,
I would like to extract average time series from my functional data using an ROI mask containing over a 100 regions. Typically, when I extract time series, I use the eigenvariate button in SPM12 (after loading a results file). However, my understanding is that this option requires specific coordinates as input. I have tried loading the mask, but the saved results only contain time series from the MNI coordinates displayed at the bottom of the menu. Is there a straightforward way to extract many time series at once using a mask (e.g. with integer values ranging from 1-100)? Any help would be greatly appreciated.
