Hi Maura,

I don't think that this mailing list is the proper forum for this type of
question. The first thing to do would be a simple google search of
"alignment scoring matrix," and then, if that is not enough, maybe someone
in your lab. Much to my supervisor's chagrin, I always come to him with very
simple questions, and his answer is always the same: "google is your
friend."
