('binary' encoding is not supported, stored as-is) Dear Amber Community,

I am trying to obtain the radius of gyration of a molecule I have
simulated. According to the below website, it is possible to do this with
carnal. I am using Amber7.
http://amber.ch.ic.ac.uk/archive/200310/0241.html
I have set up the following "script":
FILES_IN
 PARM p1 tmp56.prmtop
 STREAM s1 tmp56_bio_md3.restrt.4
OUTPUT
 TABLE p1 s1%radgyr
END

and get the following output/error message:
                          - CARNAL -
                          AMBER 6.0

                      COORDINATE ANALYSIS


input carnal.in
> FILES_IN
> PARM p1 tmp56.prmtop
Reading parm file (tmp56.prmtop)
parm: opening tmp56.prmtop
> STREAM s1 tmp56_bio_md3.restrt.4
 STREAM s1 tmp56_bio_md3.restrt.4
........^
Error in carnal.in line 3: PARM: expected ';'
    Last token was STREAM

Why does it say Amber 6.0? I have Amber7 installed and had received the
CD last November/December, shouldn't that have included Carnal 7.0?
More importantly, what do I have to do to the script I have to get a
radius of gyration for my molecule? The input is a prmtop file, and the
restart file at the end of the simulation.
Thanks for your help.

Best Regards,

Armin
