Description

Fraction of native contacts reaction coordinate (Q) trajectories for the 8 proteins that appear in the Dalton et. al. PNAS 2023. For the original all-atom data from which the Q(t) were calculated, contact the group of David E. Shaw at Shaw Research (see the paper - K. Lindorff-Larsen, S. Piana, R. O. Dror, D. E. Shaw, How fast-folding proteins fold. Science 334, 517–520 (2011))

Data contains:
- Q(t) trajectories for 8 proteins 
- Corresponding free energy profiles

Example analysis codes (written in C++) are included for:
- Free energy calculation
- Mean first-passage times
- Velocity-velocity correlation function and position-force correlation function calculations, needed for memory kernel extraction
- Memory kernel extraction (see Ayaz et. al. PNAS 2021)
