combining raw fif files w/o averaging

Hi Folks,

I am wondering if there is an easy way to combine raw fif files (i.e.,
multiple runs on a single subject) without performing any averaging. I
know it is possible to specify a grand average in mne_process_raw, but I
would like to simply combine the raw files as they are.

Thanks!

Hi,

You could use the matlab toolbox to read the raw data in and then
string them together; however, you may run into memory issues quickly
(files>2GB will be trouble). Also, you will want to be careful about
how you deal with stitching the two together i.e. your filters will
do strange things there, because there will be sharp shifts in the
data there.
