Detailed usage of daa2rma or blast2rma

Hello,
I’m a new user of MEGAN. There are many options in daa2rma and blast2rma that I don’t understand such as “–maxExpected”, “–topPercent”. And I can only find a brief description about them through the “–help” option. I wonder if there is any detailed description about them? It will be better to have a manual document.
Thanks.

There are a number of papers and book chapters that discuss these options briefly, Please also see:
