I have written some very similar in Matlab using MNE Matlab Toolbox which
does custom baseline correction and store the data back in ave fif file.
Feel free to pass by my cubicle, I am in south central infront of the back
door of MEG.

Reid,
I see. I imagine it would be possible to do baseline-correction in MATLAB
since you have a list of the latencies of each trigger (I personally don't
have experience working with the MNE MATLAB toolbox, but once you've gotten
the data into MATLAB then I imagine doing the baseline-correction should be
straightforward if you're familiar with MATLAB itself: just iterating
through each trial, selecting the proper latency from that trial from your
list, and calculating and applying a baseline-correction based on the
specific latency for that trial, then saving the data and exporting back
out to .fif). I'm not aware of a way to do this with MNE functions,
although someone else on the list might be.
Best,
Steve
