[Eeglablist] using calibration pulses and establishing 2-channel

I have two basic questions for normalizing my EEG data using EEGLAB.
1. I have a set of calibration pulses in my data. They are marked by
a "condition code" of 0. First, how can I extract just this data (I
can't find a way to select data of a specific condition code).
Second, how do I actually use the calibration pulses to normalize the
2. Our EEG is recorded as being referenced to M1. After we record, we
usually re-reference to (M1+M2)/2 by subtracting channel M2/2. In
EEGLAB, when I re-reference my data to M2, is that doing the same
thing? Or is it subtracting M2 (not M2/2)?
I took a look through the EEGLAB documentation; if these issues are
addressed there, I would appreciate a pointer to that.
Thank you very much!
