[Mne_analysis] combining/splitting fif files

[Eliezer Kanal]

Hello folks -

I have an experimental paradigm which lasts approximately 40 minutes.  
I usually just let the MEG run straight, end up with a single fif  
file, and then do all my analysis on this. We recently switched from  
16 bit to a 32 bit architecture (side point: does this mean more  
accurate recordings? what DOES that mean for the end user?), and I  
learned something new: the machine will only save files less than 2 GB  
in size. As such, I now have two files, myFile.fif (2 GB) and  
myFile_1.fif (~1.6 GB). I have no idea where it split it, behavioral- 
wise.

What's the best way to proceed from here? I can't analyze them as they  
sit, since I can't specify multiple files in mne_process_raw if the  
files contain different numbers of trials. Is there a program that can  
concatenate them? Should I just try to use mne_read_raw in matlab and  
hope matlab doesn't choke on almost 4 GB of data? Any ideas? Thanks -
