Function
Calculate fractional GC content of nucleic acid sequences
Description
geecee calculates the fraction of G+C bases of the input nucleic acid sequence(s). It sums the number of G and C bases in the input sequence(s) and writes the result to file as the fraction (in the interval 0.0 to 1.0) of the length of the whole sequence.
Usage
Here is a sample session with geecee
