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.
Check on this link...for different sequence analysing bioinformatic tools

I would recommend QIIME2 (https://docs.qiime2.org/2019.7/tutorials/). They have many tutorials that are very easy to understand and follow. The best way is to start with Moving pictures tutorial (https://docs.qiime2.org/2019.7/tutorials/moving-pictures/). They have community platform where you can ask questions and find solution to a lot of problems. You can easily perform diversity analysis, taxonomy classification and many more. They have two reference database SILVA and Greengenes for taxonomy.
I hope this helps. Let me know if you need any help.
