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
...

History

2023.1.23: Fixed issue with parameters with ‘_’

• Fixed issue with ‘-’ and ‘_’ in parameter/variable names

• Revamped documentation to the new MolSSI style and diátaxis layout.

• (internal) Moved from LGTM to GitHub CodeQL for code quality analysis

2022-6-6: Fixed bugs when editing parameters

• Also added button to remove a parameter.

2022.2.9: Added ‘files’ to parameter types

• Added ‘files’ to parameter types. Needed for job submission

2021.10.13: Cleaned up the GUI

• Made the dialog larger

• Show all parameters

• Made appropriate comboboxes read only

2021.6.3: Update for internal change in argument parsing

• Updated for the SEAMM argument parser moving to seamm_util

2021.2.9: Improved description for the installer

• Added to the README text, and made it conform to the standard style

2020.12.4: First working release

Adds functionality to SEAMM for specifying key control parameters, items such as the structure, temperature, and pressure, and use them as command-line parameters. In the future, we will also provide the ability to set them when submitting a flowchart from the Python or web interfaces.
