fa-gc

Use fa-gc to calculate the GC content surrounding a given genomic position.

The window sizes correspond to the distance upstream and downstream used to calculate GC content for. For example:

  • 50 –> “100bp” window, but a 101bp width is examined.

Example output:

> sc fa-gc --pos pos.tsv hg19.fa.gz 50 3200 500000
chrom pos gc_100 gc_6400 gc_1000000
chr1 50000 0.3663 0.373535 0.430292
chr1 50020 0.3663 0.373535 0.430288
chr1 50050 0.3564 0.373067 0.430283

Notes

  • GC content calculations omit N bases.
  • Output is sorted by chromosome, position.
