<H2> Function </H2>
Calculate the gene strand bias of the given genome

<H2>Description</H2>
<p>
ggeneskew calculates and plots the strand bias of genes (or the GC skew<br />
within them). By default, this program visualizes the gene strand preference<br />
(1 for direct, -1 for complement strand), but by specifying -base option<br />
option, GC/AT/Purine/Keto skews of the coding regions or more specifically<br />
in the GC3 (third codon position) with -gctri option can be calculated.<br />
<br />
