20# DESCRIPTION
21# This script operates on the .dat file generated by bb-matrix.sh. It tolerates
22# the header by skipping the first line, but error messages and bad data records
23# need to be removed first. It will generate three views of the plot, and leave
24# an interactive view open for further analysis.
