How to extract the peptide sequence centered the amino acid position of protein?

Question

[Lisa]

Hi, can any tools be able to extract the peptide sequence, in a certain length, centered the amino acid position of protein?

Thanks.

The question as you've stated it isn't clear to me. Can you please provide a simple example to illustrate it further?

[Lisa]

Yes, I have the chromosome and the protein position information like: chr1 230

What I want to extract is the amino acid sequence centered the chr1:230 position, with one length parameter offered L. So the actual peptide sequence is the 230-L to 230+L region on chr1.

If there is any program would automatically extract these information in batch should be convenient.

I've solved this problem.
