Samview from bam file aligned to cDNA reference

Question

[bharata1803]

Hello,

So I have a bam file from alignment to cDNA reference from Ensembl Hg38. Suppose transcript ID is T1. The length of the transcript is 15000. I want to extract the reads that aligned to T1 at position between 200-400. I think this is possible for the ordinary bam file which is aligned to human genome reference. I remember just specify chr1:pos1-pos2. How can I extract reads that correspond to a particular transcript ID and base position.

if you know the position of T1 on the genome, the process is called "translation" ...
