%GC Measure gc

This package includes a simple utility for calculating the GC content of sequence files: gc. This program will read files in raw, GCG, FastA, Genbank, or EMBL format and indicate the %GC of the file contained therein.

The general syntax of the gc command is:

gc file1 [ file2 ... ]

For example:

$ gc *.seq
ecoli1.seq: %GC = 53.7
ecoli2.seq: %GC = 44.4
salmonella.seq: %GC = 54.7
cya.seq: %GC = 51.6
