Hello, I'm trying to use mne\_average\_estimates. I created the stc files using mne\_make\_movie and the --morph tag, so according to the manual, I should not have a problem with different numbers of vertices: Note: mne\_average\_estimates requires that the number of vertices in the > stc ?les are the same and that the vertex numbers are identical. This will > be the case if the ?les have been produced in mne\_make\_movie using the > --morph option. > However, running the command results in: Checking data...[failed] Number of vertices mismatch in > 3-COMB/meg/3\_grandave The exact syntax I used for mne\_make\_movie is as below, repeated for each subject, all morphed to 4-COMB: > mne\_make\_movie --inv 10-COMB/meg/10\_grandave-meg-inv.fif --meas > 10-COMB/meg/CA10\_grandave.fif --tmin -100 --tmax 500 --tstep 1 --spm > --signed --pickupnormalcomp --subject 10-COMB --morph 4-COMB --smooth 4 > --stc 10-COMB/meg/10-COMB.stc Subject 3 seems to the be the only one with a mismatch. Any help either identifying the source of the problem, or somehow fixing it, would be much appreciated. Linnaea ---
