NAME

       psize - Get dimensions and other information from PQR files

SYNOPSIS

       psize [--cfact=value] [--fadd=value] [--space=value] [--gememfac=value] [--gememceil=value] [--ofrac=value] [--redfac=value] {pqrfile}

       psize {--help | -h}

DESCRIPTION

       psize derives information from PQR files to preprare the models of proteins and chemicals for electrostatics calculations. The tool
       calculates dimensions for coarse and fine grids, grid spacings, box size and estimates the memory required to perform an electrostatics
       calculation.

       The calculation of this information can be influenced by giving constraints to psize as parameters.

OPTIONS

       psize accepts the following options:

       --help, -h
	   Print a help message and exit.

       --cfact=value
	   Factor by which to expand the molecule dimensions to get the coarse grid dimensions

       --fadd=value
	   Amount to add to the molecule dimensions to get the fine grid dimensions.

       --space=value
	   Desired fine mesh resolution.

       --gememfac=value
	   Number of bytes per grid point required for sequential MG calculation.

       --gememceil=value
	   Maximum MB allowed for sequential MG calculation. Adjust this to force the script to perform faster calculations (which require more
	   parallelism).

       --ofrac=value
	   Overlap factor between mesh partitions.

       --redfac=value
	   Maximum factor by which a domain dimension can be reduced during focusing.
