[Mne_analysis] Error using mne_average_estimates

[Stephen Politzer-Ahles]

Hi Alex,

Thank you. Here are links to two of my stc files and to the
mne_average_estimates description file:
http://dl.dropbox.com/u/9929284/AL023_ave-rh.stc
http://dl.dropbox.com/u/9929284/AL023_ave-lh.stc
http://dl.dropbox.com/u/9929284/stcdescrip

I made the stc files using the following command line:

mne_make_movie --subject $SUBJECT --meas
> $SAMPLE/MEG/$SUBJECT/$SUBJECT"_ave.fif" --inv
> $SAMPLE/MEG/$SUBJECT/$SUBJECT"_ave-7-meg-inv.fif" --morph average --smooth
> 5 --stc $SAMPLE/MEG/$SUBJECT"_ave"
>

(My directory structure is, within $SAMPLE I have a /subjects folder with
the MRI data and an /MEG folder with the MEG data.) I didn't use the --bmin
and --bmax options because I already did baseline correction when I
averaged the MEG data.

After creating stc files like that for every subject, I ran

mne_average_estimates --desc stcdescrip

using the attached description file.

Best,
Steve
