mne.read_source_estimate(fname, subject=None)

• for volume source estimates, fname should provide the path to a single file named ‘-vl.stc or ‘-vol.stc’
• for surface source estimates, fname should either provide the path to the file corresponding to a single hemisphere (‘-lh.stc’, ‘-rh.stc’) or only specify the asterisk part in these patterns. In any case, the function expects files for both hemisphere with names following this pattern.
• for single time point .w files, fname should follow the same pattern as for surface estimates, except that files are named ‘-lh.w’ and ‘-rh.w’.
