performed with the help of mapping files that associate the specific naming conventions in each simulation with the universal molecule and atom names used by the Databank. Finally, the analysis results can be stored using the same structure as in the Databank layer. Documentation of the NMRlipids Databank-API and template for new user-defined analyses with further instructions are available at the NMRlipids databank documentation . While analysis codes and results for basic membrane properties are included in the Databank layer, unlimited further analyses can be implemented by anyone in separate repositories in the Application layer. When Application layer repositories are organized by mimicking the Databank layer structure, they can be accessed programmatically and further analyzed using the tools in the NMRlipids Databank-API by implementing the flowchart demonstrated in Fig. . Novel analyses that demonstrate the power of NMRlipids Databank in selecting the best simulation models, analysing rare phenomena, and extending MD simulations to new fields are implemented in an Application-layer repository located at github.com/NMRlipids/DataBankManuscript. The related codes are listed in Table .
