Optional Parameters¶

Execute Options¶

-param¶: The argument for this flag is the name of a file containing control parameters. The control parameter file acts to either replace or augment the command line interface. All parameters necessary for program execution may be provided in the control parameter file, although any command given explicitly on the command line will supersede options found in the parameter file. The application generates a new parameter file containing the full set of execution parameters upon every execution. The name of the parameter file is created by combining the prefix base name with the ‘.param’ extension.

-mpi_np <n>¶: Specifies the number of processors n when the application is run in MPI mode.

-mpi_hostfile <filename>¶: Specifies the name of the file containing processors configuration. For every host this file should contain a line host_name slots=n where n is the number of processors on the host.

File Options¶

-log¶: The argument for this flag specifies the name of the log file. The level of detail for logfile information can be altered using the -verbose flag. Generation of an output log may be disabled by providing nul as a argument in Windows and /dev/null as an argument on Linux and macOS. [default = prefix _log.txt]

-prefix¶: The argument for this flag defines the prefix to be used for various information and data files generated. Most important among these is the ‘prefix_parm.txt’ file which includes a copy of all the parameters used in the run. The prefix is also used to generate a default log file name if not explicitly specified with the -log flag. [default = <app_name>].

-verbose¶: This is a boolean flag that controls the level of detail written to the log file. By default only minimal information is written to the log file. Verbose logging will cause more information to be written to the log file in order to follow behavior during program execution. [default = false]

-molNames¶

This parameter takes a text file containing a list of molecule names (one name per line in the file). If this parameter is set then only molecules in the input file(s) (see parameter -in) with names that match those in the text files will be read in.

The general purpose of this flag is to provide an easy mechanism for reading a few specific molecule(s) that are contained in a large file, without having to extract those molecules by hand from the input molecules file. [default = NONE].

-progress¶: Show progress on screen. Options are ‘none’, ‘dots’, ‘log’ and ‘percent’. The ‘dots’ options will displays dots on screen to show molecules completed. The ‘log’ option will duplicate the log file on screen. The ‘percent’ option will track progress through the input file. [default = none]

EON App Options¶

-fixpka_query¶: Apply a neutral pH model to the query molecule. It should be set to false if -charges is set to existing; otherwise EON will fail. [default = true]

-fixpka_dbase¶: Apply a neutral pH model to the database molecules. It should be set to false if -charges is set to existing; otherwise EON will fail. [default = true]

-writegrid¶: Whether or not to output electrostatic grid when writing to .oeb file. [default = false]

EON Overlay Options¶

-charges¶: Specifies charges to be used on the query and the database. Default is to calculate them internally with mmff. The option -charges existing will use precalculated charges that must be set in the input files. If existing is selected and any molecule doesn’t have charges then EON will default to mmff for those molecules. Both -fixpka_query and -fixpka_dbase should be set to false if -charges is set to existing; otherwise EON will fail. [default = mmff]

-num_top_scores¶: When potential mode is engaged, the shape and charge overlay will keep this many best hits, and score them all with potential to choose best combo hit. [default = 5]

-potential¶: Scoring done with shape and potential similarity combo. [default = false]

EON Hitlist Options¶

-besthits <N>¶: Keep a hitlist. Zero implies score and output all. [default=1000]

-maxhits <N>¶: Stop after finding first N hits. [default=0]

-cutoff <N>¶: Minimum score to keep. [default=-1.0]

ZAP/PB Options¶

-dielectric¶: Sets the dielectric constant. [default = 80.0]

-gridBuffer¶: Sets the grid buffer. [default = 6.0]

-gridSpacing¶: Sets the grid spacing for the internal Zap calculations. [default 0.75]

-innerMask¶: Sets the grid inner mask for the internal Zap calculations. [default 0.05]

-outerMask¶: Sets the outer mask for the internal Zap calculations. [default 0.0005]

-saltConc¶: Sets salt concentration for the internal Zap calculations. [default 0.04]
