[Mne_analysis] question regarding mne_do_forward_solution

[dgw]

HI Andrew,

My reading of that is that you should use an average file for --meas
if you are processing averaged data, and a raw file if you are
processing raw data. I do not believe that there are any issues with
having multiple average files from the same raw data file and only
using one forward solution calculated from one of the average files.
Just that it is not recommended that you use the raw file to generate
the forward solution.

as always if I'm wrong please say so
