Hello,
I have noticed that the introductory tutorial parameter and topology files
for starting a NAMD simulation (the protein in the tutorial is ubiquitin)
are named:
par_all27_prot_lipid.inp
top_all27_prot_lipid.inp
whereas the names obtained from CHARMM-GUI/CHARMM are:
par_all36m_prot.prm
top_all36_prot.rtf
The files from the tutorial obviously run when following the tutorial for
setting up and running a simulation on my home computer, but the files from
CHARMM/CHARMM-GUI do not run. Additionally, as I understand it, the
tutorial files are somewhat out of date (RMSF profiles from both file
sources are vastly different).
My question then is, how do I obtain parameter and topology files that are
the most recent *that I can use directly into NAMD and VMD* so that both
NAMD and VMD will take them like the tutorial files? Preferably, I would
like to have NAMD-compatible top and par files that are the equivalent of
charmm36m. Thanks.
