tools to get coverage of a particular transcript from bedgraph

Question

[manauwer_raza]

I have a bedgraph.

1    0    10540    0
1    10540    10564    4
1    10564    10569    5
1    10569    10590    7
1    10590    10614    3
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.
