CAMISIM is a software to model abundance distributions of microbial communities and to simulate corresponding shotgun metagenome datasets. It was mainly developed for the Critical Assessment of Metagenome Annotation (CAMI) challenge, but should be suitable for general use. Please don't hesitate to open a new issue if you run into problems or need help.
