Dear Amber Users,
I am trying to use anal to do Energy component analysis (though there is
reported bugs for this feature I wanted to see how it
works. Hopefully AMBER 7 will have everything fixed)) and also
sugar puckering. I have a 10 base pair B-DNA solvated with water and ions. 
I used the follwing commands
anal -O -i anal_in_pucker -o anal.out -p double.top -c md_prod.restart
In both cases I get the following output only. It seems anal does not do
anything. At the end of the output I have appended the anal.in file. Can
someone suggest a remedey.
