How to input parameters in NuProt Calculator

I would like to use the NucProt Calculator for an RNA/protein mix, more exactly the genome of a virus plus several copies of its viral enzymes. I am not sure how I should input things in the program. Shall I introduce the sequence of the viral genome followed by those of the viral proteins?

The NucProt Packing-Eff calculator works on PDB structures NOT sequences, so they cannot mean that:

The NucProt PSV and Volume Calculator:
http://www.molmovdb.org/cgi-bin/psv.cgi
is not the best written CGI code that can take several sequences at once, but since I didn't understand HTTP GET and POST very well, I had it put all in the information in the GET rather than the POST, so there is a browser limit. I don't think I have write access anymore to this file.

Technically it can take several sequence in FASTA format though.
