Hi All,

I want to generate psf file for DNA using CHARMM force field. The topology
file for nuclic acid contains the connectivity of ribose sugar. But I need
the connectivity of deoxyribose sugar. So I have to replace the OH (O2'-H2')
group by H (H2') atom.

Can anyone pls suggest me what will be the keyword or command that will be
written in the *.in *file so that I can get the psf file of DNA.
