Executables that aren't available on TACC through the "module" command should be stored in $HOME.
If you plan to be using a set of files frequently or would like to save the results of a job, they should be stored in $WORK.
If you're going to run a job, it's a good idea to keep your input files in a directory in $WORK and copy them to a directory in $SCRATCH where you plan to run your job.
This example command might help a bit:
cp $WORK/my_fastq_data/*fastq $SCRATCH/my_project/
