Permutationally Invariant Networks for Enhanced Sampling (PINES): Discovery of Multi-Molecular and Solvent-Inclusive Collective Variables

Implementation of PINES in PLUMED2

Requirements

• PLUMED2
• MD Engine (GROMACS)

Installation

Case 1: With installed PLUMED2+MD,

• Follow this for reinstalling PLUMED with PINES:
  • Download this repository
  • Execute patch_piv_mesa_plumed.sh <path_to_PLUMED>
  • Re-install PLUMED2 with --enable-modules=all or --enable-modules=pines+annbfunc
• Alternative usage without reinstalling PLUMED:
  • use LOAD command in PLUMED to link in plumed.dat file with the PINES codes in this repository. Example usage can be found in examples/driverTests.

Case 2: New installation of PLUMED2+MD,

• Download this repository
• Download MD Engine & PLUMED2.
• Execute patch_piv_mesa_plumed.sh <path_to_PLUMED>
• Follow standard MD Engine + PLUMED2 installation process with --enable-modules=all or --enable-modules=pines+annbfunc

Examples

• Argon 13 cluster
• C45 in water
• NaCl in water

Parameters

Please refer parameters.md for a template PLUMED file along with annotations explaining each parameter. In case the annotations are not clear, please let us know by opening an issue in this repo.
