Test compatability of contigs between a sample BAM file and a reference genome FASTA file.

Question

[r.kalampaliki]

A have a sample BAM file from which I don't know the reference genome. Is there any way (ex.samtools command) that I could find its reference genome?

I was think that checking the compatability of contigs between the BAM file and some canditates as reference genome FASTA files could do the job, but is there any tool checking for the compatability of contigs?

Thank you.
