Akshata,
Simply, try to put parameter file in the same directory where is
NAMD.exe file. To do this check did you have read/write permission,
because newer OS like Win7 can make problems. Otherwise, put parameter
file to other directory, but be sure that you have no spaces in path
'name', for example 'D:/namd_working_dir/par_all27 _prot_lipid.inp.
Also, try to use file with '_prm_' extension for _simulation_. If you
need CHARMM27 parameters, you can download it from:
http://mackerell.umaryland.edu/charmm_ff.shtml
file: 'toppar_c32b1.tar.gz'
