MacroModel was originally developed at Columbia University Chemistry and is now part of Schrödinger's molecular modeling software. An MMOD file stores data used in MacroModel molecular mechanics work, including a molecular model and information needed for the associated calculation.
The file belongs to the MacroModel software environment rather than being a general-purpose molecular structure format. Its MIME type is chemical/x-macromodel-input.
MacroModel is available through Schrödinger's software for supported Windows, Linux, and macOS systems. MMOD remains a specialized format intended for use with MacroModel.
Open an MMOD file with MacroModel from Schrödinger. Install MacroModel on a supported Windows, Linux, or macOS system, then use its Open command to load the file.
Because MMOD is a specialized MacroModel format, general-purpose text editors and molecular viewers may not interpret its contents correctly.
Open the file in MacroModel and use the program's save or export commands if a different molecular or calculation format is required.
