##Running

HLFRED requires that you have the enviroment variables HLFRED_DSDIR and HLFRED_RUNDIR set for the input and output directories or you supply them on the command line. HLFRED will look for input data in HLFRED_DSDIR/my_dataset_name and will copy these data to HLFRED_RUNDIR/my_dataset_name and process the data in run directory.

Here's a simple shell script to run all tasks with the input data in a directory HLFRED_DSDIR/test_hlf:

#!/bin/bash
export HLFRED_DSDIR="/Volumes/DataRaid1/Data/DATASETS"
export HLFRED_RUNDIR="/Volumes/DataRaid1/Data/REDUCED"
DSN="test"

## For ACS/WFC data
# for task in init ampc amsk drzi mcat saln apsh drzm
## For WFC3/UVIS data
# for task in init amsk drzi mcat saln apsh drzm
# For WFC3/IR data
for task in init amsk ssub drzi mcat saln apsh mivm drzm
do
	hlfred $DSN $task
	ret=$?
	if [[ $ret = 0 ]]; then
	    echo "HLFRED task ${task} completed"
	else
	    echo -e "\033[0;31mERROR: HLFRED task ${task} failed.\033[0m"
		exit 1
	fi
done
