# DESCR.: Create trace masks for a list of files in a given directory -
#         and a given parameter file. Save output masks and logfile in
#         convenient directory structure.
# USAGE:  ctrace.sh <parameter_file>, where <paramter_file> 
#         sets variables mainpath=, night=, userparfile=, parfile=,
#         inputfiles= and masterbias=
#         (for example parameter file see ./ctrace.params)


# test if argument is provided is provided and file is existent
if [ -z "${1}" ] || [ ! -f ${1} ]; then
    # .. if not, quit gracefully!
    echo "Supply parameter file as argument!"
    exit 0
