1 ggenomicskew
2 Function
3
4 Calculates the GC skew in different regions of the given genome
5
6 Description
7
8 ggenomicskew calculates and plots the GC skew for the whole genome, coding
9 regions, intergenic regions, and the third codon. This program is useful in
10 visualizing various base composition bias within the genome. AT skew can be
11 calculated instead of GC skew by toggling the -at qualifier.
