Averaging together stc files from multiple subjects

Dear MNE users,

I'm running source localisation (using lcmv beamformer) on a number of subjects. So far I have generated source estimates in the form of a .stc file for each individual subject, and then morphed these to a common cortical surface. I can visualise each of these individually, using brain = stc.plot. Is it possible to create a 'group average' source estimate, from the individual .stc files, for visualisation purposes?

Regards

Lyam

Hi Lyam,

You can simply add common space MORPHED stc files by

stc = stc_a + stc_b

If you want to do something more fancy and know what you are doing

stc = stc_a.copy()

stc._data = stc_a._data + stc_b._data
