# table.sh file, part of RACS ORF pipeline
#
# This script is internal to the RACS ORF pipeline, and it is called from
# "countReads.sh"
# However this script can be used separatedly for generating
# tables of ORF for a given organism and targets
#
# The script accepts two arguments:
#
#  1st) a mandatory argument specifying the name of the reference file (gff3)
#
#  2nd) an optional argument indicating the configuration file of the target
#  terms to identify within the reference file.
#  If the second argument is not indicated, the script will assume the
#  definitions for the Tetrahymena Thermophila provided by our pipeline
#  included in the "TT_gene.id" file
