i want to analyze the change of secondary structure of the mainchian frome
residue 20 to residue 60. so i want to make a index file that only contain
the maninchian+H from residue 20 to residue 60. i have inputed the command "
make_ndx -f em.pdb -o index.ndx", but i don't kown how to do next . what
should i input ? thank you very much!
A good place to start is to type "help" at the prompt to see full syntax
information and examples. In this case, creating the group is very easy:
7 & r 20-60
This tells make_ndx to merge (using &) the common parts of group 7 (MainChain+H)
and residues 20-60.
