Is it possible to run ModRefiner with the gnuparallel option?

1. When using the standalone version of I-TASSER, have the final models been refined with ModRefiner or is it necessary to submit one or more models from the I-TASSER output to ModRefiner?

2. Could you please give the exact syntax for specifying the various options when running the standalone version of ModRefiner?

3. Is it possible to run the standalone version of ModRefiner using -runstyle gnuparallel so that I can use all available cores in my workstation?

Thank you.
