Automatic NAMD System Input Builder

Pestifer is a Python utility for generating atomistic inputs with appropriate topology and parameter files required for molecular dynamics simulations using NAMD. It is intended as a fully automated system builder requiring as inputs only the PDB codes of biomolecular structures and a handful of customization parameters. Pestifer primarily works as a front end for VMD's psfgen utility.

pip install pestifer

Once installed, the user has access to the main pestifer command.

• 1.4.1:
  • support for empty TER records
• 1.4.0:
  • packmol-memgen integration
• 1.3.9:
  • added include_C_termini boolean to declash directives; set to False to prevent C-terminal insertions from undergoing automatic declashing
• 1.3.8
  • bugfix: spurious code in pestifer-vmd.tcl
• 1.3.7
  • bugfix: fixed a spurious hard-coded path in macros.tcl
• 1.3.6
  • bugfix:
    • runscript sources TcL proc files with dependencies in proc files that aren't yet sourced; fixed that
  • alphafold source directive added to permit download of models from the AlphaFold database by accession code
• 1.3.5
  • bugfix:
    • renumbering of author resids in non-protein segments if user adds protein residues by insertion that may conflict
