The fact is, everyone who asks a question wants an answer as quickly as possible. Can you guess how few people will ask a question, but not really care when they get an answer? Next week, next month, oh just whenever someone gets around to it. That you need it now is just a reflection that you should manage your time better in the future. Sorry, but true.

Your question will get an answer when someone sees it who knows how to solve your problem, AND who has the time and inclination to answer.

Dear john., Sorry first of all. The reason I include the word 'quickly' means I have already post this same question one month ago, still I didn't get any answer. That's why I post like this this time. No need to tell sorry to me, I agree whatever you mentioned is right.

Attach some representative samples of your protein sequences to your original post or to a Comment to it here, preferably as a ‘.mat’ file. Include a complete table of the amino acid name abbreviations you are working with.

What Toolboxes (for example the Bioinformatics Toolbox) are you using? Not all of us have all the Toolboxes, so we may not be able to help you with problems that require specific Toolboxes.
