TRATES

TRAnsporter TErmini Simulations

TRATES is a tool that prepares all of the files that are necessary for molecular dynamics simulations and provides analysis of simulation data for glucose transporter termini.

Installing TRATES

TRATES can be easily installed with:
pip3 install git+git:https://github.com/Kobie-Kirven/trates

Using TRATES

TRATES is made up of several subpackages including

  • trates-prepare
  • trates-rmsd
  • trates-contacts
  • trates-plot

TRATES Command Line Options

Trates Prepare:
