I have a bedgraph.

1    10540    10564    4

1    10614    10619    2
1    10619    12045    0

from reads mapped to the genome. now I want to extract a particular transcript

1    925741    944581

from the bedgraph, which would give me only those cordinates and coverage of the transcript provided.

Are there any tools to do this job?

I can write perl script to do this, but I have many transcript to find out, please suggest me with a tool, if available.
