I have 16s metagenomic raw data to be analysed , please describe me different software and its work application to analyse it with respect to diversity ?
You can try using Mothur to process your metagenomic data, which helps you in classification of microbial community in a particular environment.Also as there is interface in java where you don't need a command line.
Yet another option is MG-RAST where automatic analysis of metagenomes for function,phylogeny etc can be done.
