applique 0.1.14

Chemical drawing with Python

applique

applique is a simple program that can write .xyz file from .mol files. It really is just a missing puzzle piece in the quantum chemistry world, as some molecular editors went corrupt. Now one can use common Quantum Chemistry software again. It mimics Avogadros behaviour.

Nothing special.

Okay by now it is an understatement. It is infact a molecular model suitable for generating simulations. It can also convert fileformats.

Installation

Simple as always

pip install applique

Usage

Cli

In your venv

applique --i in_file.mol --o out_file.xyz

Easy peasy

Programs

Within programs for example you load a molfile like this

from applique.molecule import Molecule as Mol

mol_file_benzene = "tests/molecules/benzene.mol"
benzene = Mol().from_mol(mol_file_benzene)

Then write the .xyz like this

from applique.writer import write_xyz
from applique.molecule import Molecule as Mol

mol_file_benzene = "tests/molecules/benzene.mol"
benzene = Mol().from_mol(mol_file_benzene)
file_name_benzene = "./tests/molecules/benzene.xyz"
coordinates = benzene.struct3D() #you can omit if you don't want to preoptimize the structure.
write_xyz(self.benzene, file_name_benzene)

Errors

This is wanted (don't want to impose bonds at this stage)
