Hi,

I have aligned 5 bacterial genomes using the progressiveMauve. I would like to extract the part of the alignment having sequence in all the genome (eg: second and fourth line positions) using the alignment(.xmfa) file and backbone(.backbone) file.

seq0_leftend seq0_rightend seq1_leftend seq1_rightend seq2_leftend seq2_rightend seq3_leftend seq3_rightend seq4_leftend seq4_rightend
0 0 23127 23463 20107 20443 32207 32543 29528 29864

-27824 -28003 23815 23997 20795 20977 32895 33077 30216 30398

Is there any utility to achieve this task? How to extract only the lines having sequence from all the genomes(e.g., 2nd, 4th)?

Thanks.
