TS2CG: Triangulated Surfaces to Coarse-Grained
TS2CG
converts triangulated surfaces (TS) to coarse-grained membrane models for molecular simulation. It also works as a backmapping algorithm from dynamically triangulated surfaces simulations to CG molecular dynamics simulations or to take electron microscopy tomography data and build structures for molecular dynamics simulations.

Backward
Backward is a tool to convert a coarse-grained system to united-atom or all-atom resolution. The mapping is done using a library of mapping definitions, which encode the geometric reconstruction. The tool consists of three scripts and a number of CG to fine-grained mapping definition files.
