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.
In most cases, the backmapping is performed using the wrapper initram.sh, which calls backward.py and subsequently relaxes the resulting structure through energy minimization and molecular dynamics based relaxation.

When your system has lipids, we recommend downloading the mapping files for them from the lipidome library.
