I am trying to relax my protein with following parameters, but it failed with messages:
core.pack.task: Packer task: initialize from command line()

You're getting that error message because you didn't specify a loops file.
I'm not sure why it would be looking for a loops file, though. From the options you posted, the relax application shouldn't need a loops file. What's the commandline that's printed in the very top of the log which shows this message? (It looks like it may be different from what you're expecting, as the log looks like it's working on a file called "nvt.pdb" rather than "input.pdb".) Also, are you using the relax application (e.g. relax.default.linuxgccrelease") or are you doing the relax through some other method?
