- access to NIST EI and MS/MS library search algorithms directly from R;
- compatibility with proprietary mass spectral libraries (e.g., NIST23);
- automated processing and organization of search results;
- support for parallel computation;
- availability on Windows, Linux, and macOS (Wine must be installed on Linux and macOS).
