A SEAMM plug-in for defining command-line parameters for a flowchart.

Control Parameters Step

Description

A SEAMM plug-in for defining command-line parameters for a flowchart. This plug-in provides a step in a SEAMM flowchart where a user can define required and optional arguments for the flowchart as a whole. When the flowchart is run, the command-line is parsed and the arguments placed in variables that can then be used by other steps.

This can be used to pass file names or SMILES strings for the molecules to run; or give the temperature and pressure; or any appropriate parameters that the flowchart author feels are relevant.

When run from the command-line, giving the option –help provides help on these control parameters as well as other options for the run:

bash-3.2$ ../flowcharts/psi4.flow --help
usage: ../flowcharts/psi4.flow [options] plug-in [options] plug-in [options] ...

positional arguments:
  SMILES                The SMILES string for the input molecule

optional arguments:
  -h, --help            show this help message and exit
  --method {b3lyp-d3mbj,mp2,ccsd}
                        The type of calculation
...
