MSR

Microstate sparse reconstruction, an optimization algorithm that solves the inverse problem: recovering an all-atom state consistent with a coarse-grained description.

PREREQUISITES

ProtoMD - https://github.com/CTCNano/proto_md

PETSc - https://www.mcs.anl.gov/petsc

MDAnalysis - https://code.google.com/p/mdanalysis

Numpy - http://www.numpy.org

WORKING EXAMPLE

python MSRWriter.py struct traj tpr tol

-struct: structure file such as a pdb or gro file

-traj: trajectory file such as a trr, xtc, or dcd

-tpr: binary input file generated by Gromacs (with grompp) for reading topology

-tol: tolerance set for the atomic displacement, below convergence is assumed to be achieved
