Other options

-h [ –help ] [=arg(=SHORT)]

Print help message and exit (ABOUT, USAGE, SHORT, ALL or ‘name of option’, default: SHORT).

-V [ –version ]

Print version information and exit.

-v [ –verbosity ] [=arg(=VERBOSE)]

Verbosity level of information output (QUIET, ERROR, INFO, VERBOSE, DEBUG, default: INFO).

-c [ –config ] arg

Use file with program options.

-l [ –log-file ] arg

Redirect text-output to file.

-p [ –progress ] [=arg(=1)]

Show progress bar (default: true).

-I [ –input-format ] arg

Allows to explicitly specify the format of the input file(s) by providing one of the supported file-extensions (without leading dot!) as argument.

Supported Input Formats:
  • JME Molecular Editor String (.jme)

  • MDL Structure-Data File (.sdf, .sd)

  • MDL Molfile (.mol)

  • Daylight SMILES String (.smi)

  • Daylight SMARTS String (.sma)

This option is useful when the format cannot be auto-detected from the actual extension of the file(s) (because missing, misleading or not supported).
