Dear Xiang-Jun,
1) I would appreciate a --silent option since I am running your programs on a large number of files.
2) with snap, I would appreciate a count of the files that are written out by your program and something like a zero output file message if they are no proteins processed. This would be helpful for parsing (I know that there is a screen message, but writing it in the output file should be interesting).
Thanks for considering this if you have time.
Best,
Pascal
