# Computational Chemistry Input Generator [![codecov](https://codecov.io/gh/cyllab/ccinput/branch/main/graph/badge.svg?token=ox4smJs0vh)](https://codecov.io/gh/cyllab/ccinput) [![PyPI version](https://badge.fury.io/py/ccinput.svg)](https://badge.fury.io/py/ccinput) [![Downloads](https://pepy.tech/badge/ccinput)](https://pepy.tech/project/ccinput) [![DOI](https://zenodo.org/badge/DOI/10.5281/zenodo.5907043.svg)](https://doi.org/10.5281/zenodo.5907043) `ccinput` is an application to generate input files for computational chemistry software. Example usage: ``` $ ccinput gaussian opt M062X -bs def2tzvp -f ethanol.xyz -n 8 --mem 32G %chk=calc.chk %nproc=8 %mem=32000MB #p opt M062X/Def2TZVP File created by ccinput 0 1 C -1.31970000 -0.64380000 0.00000000 H -0.96310000 -1.65260000 0.00000000 H -0.96310000 -0.13940000 -0.87370000 H -2.38970000 -0.64380000 0.00000000 C -0.80640000 0.08220000 1.25740000 H -1.16150000 1.09160000 1.25640000 H -1.16470000 -0.42110000 2.13110000 O 0.62360000 0.07990000 1.25870000 H 0.94410000 0.53240000 2.04240000 $ ccinput orca sp DLPNO-CCSDT -bs cc-pVTZ -f *.xyz -o .inp -n 32 --mem 250GB --parse_name *** No C auxiliary basis set specified, using cc-pVTZ *** *** No C auxiliary basis set specified, using cc-pVTZ *** *** No C auxiliary basis set specified, using cc-pVTZ *** *** No C auxiliary basis set specified, using cc-pVTZ *** Input file written to carbo_cation.inp Input file written to CH4.inp Input file written to ethanol.inp Input file written to H2.inp $ cat H2.inp !SP DLPNO-CCSD(T) cc-pVTZ cc-pVTZ/C *xyz 0 1 H -1.43860000 -0.26820000 0.00000000 H -2.03860000 -0.26820000 0.00000000 * %MaxCore 7812 %pal nprocs 32 end $ cat carbo_cation.inp !SP DLPNO-CCSD(T) cc-pVTZ cc-pVTZ/C *xyz 1 1 C -2.90770000 1.66310000 0.00000000 H -2.55100000 2.16750000 0.87370000 H -3.97770000 1.66310000 0.00000000 H -2.55100000 2.16750000 -0.87370000 * %MaxCore 7812 %pal nprocs 32 end ``` `ccinput` can also be used as python library: ``` >>> from ccinput.wrapper import gen_input >>> inp = gen_input(software="orca", type="ts", method="PBEh-3c", file="ethanol.xyz", nproc=16, solvent="ethanol", solvation_model="SMD") *** No solvation radii specified; using default radii *** >>> print(inp) !OPTTS PBEh-3c *xyz 0 1 C -1.31970000 -0.64380000 0.00000000 H -0.96310000 -1.65260000 0.00000000 H -0.96310000 -0.13940000 -0.87370000 H -2.38970000 -0.64380000 0.00000000 C -0.80640000 0.08220000 1.25740000 H -1.16150000 1.09160000 1.25640000 H -1.16470000 -0.42110000 2.13110000 O 0.62360000 0.07990000 1.25870000 H 0.94410000 0.53240000 2.04240000 * %pal nprocs 16 end %cpcm smd true SMDsolvent "ethanol" end >>> ``` ## Installation ### From PyPI ``` pip install ccinput ``` ### From Github You can install the bleeding-edge version of `ccinput` from Github: ``` pip install git+https://github.com/cyllab/ccinput ``` ## Usage `ccinput` supports a wide range of options, including different solvation radii, density fitting and multiple basis sets. As of now, Gaussian 16, ORCA 5 and xtb are supported, and more packages will be added in the future. ### From the command line Simply use the `ccinput` command with the desired parameters: ``` usage: ccinput [-h] [--basis_set BASIS_SET] [--solvent SOLVENT] [--solvation_model SOLVATION_MODEL] [--solvation_radii SOLVATION_RADII] [--custom_solvation_radii CUSTOM_SOLVATION_RADII] [--specifications SPECIFICATIONS] [--density_fitting DENSITY_FITTING] [--custom_basis_sets CUSTOM_BASIS_SETS] [--xyz XYZ] [--file FILE [FILE ...]] [--output OUTPUT] [--constraints CONSTRAINTS] [--freeze ATOM [ATOM ...]] [--scan ATOM [ATOM ...]] [--from FROM] [--to TO] [--nsteps NSTEPS] [--step STEP] [--nproc NPROC] [--mem MEM] [--charge CHARGE] [--mult MULT] [--parse_name] [--trust_me] [--d3 | --d3bj] [--name NAME] [--aux_name AUX_NAME] [--header HEADER] [--save SAVE] [--preset [PRESET]] [--driver {none,ORCA,pysis}] [--version] [--fragments FRAGMENTS] [software] [type] [method] ``` More detailed information about each option can be obtained with the `ccinput -h` command. ### As Python library The function `gen_input` returns input files as a single strings with the correct whitespace. ``` >>> from ccinput.wrapper import gen_input >>> inp = gen_input(...) ``` The input can also be directly written to a file using `write_input`. ``` >>> from ccinput.wrapper import write_input >>> write_input(filename, ...) ``` See the [documentation](https://ccinput.readthedocs.io/en/latest/usage.html) for all options. ## Contributing We welcome all contributions to the project. This includes: - Support for new packages (even if rudimentary) - Support for new features of supported packages - Correction or improvement of static data (like DFT functionals or basis sets) Planned tasks are listed in the [roadmap](https://github.com/orgs/cyllab/projects/1/views/1). This can be a good place to start when looking to contribute, although do not limit yourself to what is listed there. The contribution guidelines are detailed in CONTRIBUTING.md.
