A small package for making point cloud objects whole in the presence of PBC

Project description

mdvwhole

Density based object completion over PBC. This repository will eventually be merged with MDVoxelSegmentation.

No copies of the box are made to complete the PBC, instead we use a graph based approach. Therefore object completion is very light on memory and can cover an arbitrary amount of consecutive PBC crossings.

How to cite

For now it is best to cite the original MDVoxelSegmentation article with the note that you used the new beta 'Whole' feature.

Install

pip install mdvwhole

Usage

Making a single gro whole:

mdvwhole -f your_gro.gro -x your_gro -o whole.gro

Making a trajectory whole:

mdvwhole -f your_gro.gro -x your_xtc -o whole.xtc

Using a non-default selection:

mdvwhole -f your_gro.gro -x your_xtc -o whole.xtc -sel 'not resname W WF ION and not name PO4'
