Hi, Julien
 
 You need to have a matching prmtop and PDB file to use carnal. Here is a 
 
sample carnal input to calculate radius gyration
 
 FILES_IN
 
         PARM p1 _your_prmtop_;
 
         STREAM s1 _your_PDB_;
 
FILES_OUT
 
         TABLE t1 radgyr.tbl;
 
DECLARE
 
         GROUP grpid1 (_your_selection_);
 
OUTPUT
 
         TABLE t1 grpid1%radgyr;
 
END
