Low complexity and high complexity datasets generated in metaSPARSim

Hello,

First of all thank you for your metaSPARSim tool for helping us to create simulated 16S data for benchmarks studies.

I'm trying to create a simulated data. In detail, I would like to create a dataset with low diversity communities and other with complex and rich communities.

However I am not able to see if it is possible to cope this goal through your software or not, because I do not want to create a simulated data from real data (case2 and 3 from your MetaSparSim BMC informatics paper) and then I have only the possibility of direct specification, but have you cot some available to create authomatically the vector of species abundances in order to create a low/complex communities?

thanks on advance for your help,

David.
