OpenmRNABam: This function loads Bam files generated by local mapping with bowte in oneChannelGUI
Description
The function creates and expressionSet starting from the association of reads mapped by Bowtie using
chromosome oriented mapping controlled by oneChannelGUI and associate those mapping to gene-level
regions extracted by UCSC browser.
IMPORTANT at the present time the expression set is base on gene-level data and not on exon-level data.
