[citation needed] In successive releases IMG has expanded to include several domain-specific tools.

The Integrated Microbial Genomes with Microbiome Samples (IMG/M) system is an extension of the IMG system providing a comparative analysis context of assembled metagenomic data with the publicly available isolate genomes.

[2] Users can submit their annotated genomes (or request the IMG automated annotation pipeline to be applied first) into IMG-ER and proceed with manual curation and comparative analysis in the system, through secure (password protected) access.
