Hi, Chi!
I checked out (from scratch) from CVS as specified in the previous email.
I should now have everything like the blast account, right?
How did you get e-p events?
If I run nsed (not my own cruncher) again and look for the results you
mentioned:

... this is what I get for first two events (145 and 229):

They do not look like e-p events here... I agree they look nice on the
nsed display, but how can I know they are e-p if nsed misidentifies them?
How can I reproduce your nsed's results (or how do you know they were
e-p)?
Thanks for looking into this!

Adrian
