FRETraj is a Python module for predicting FRET efficiencies by calculating multiple accessible-contact volumes (multi-ACV) to estimate donor and acceptor dye dynamics. The package features a user-friendly PyMOL plugin1 for for FRET-assisted, integrative structural modeling. It interfaces with the LabelLib library for fast computation of ACVs. Specifically, FRETraj is designed to:
- plan (single-molecule) FRET experiments by optimizing labeling positions
- interpret FRET-based distance measurements on a biomolecule
- integrate FRET experiments with molecular dynamics simulations
