How to create OTUs from 16S rRNA sequence FASTA file to species level with metagenomic data analysis? (Step by Step)

Question

[Clark_BioMorgan]

I have data of sequences from a sample and would like to diverse them in intervals based on similartiy to references with 97% as same species, 97%-95% smilartiy is same genius and goes on. I have raw 16S rRNA data and would like to star with sequence data as FASTA file and continue from there with trimimn , alignment and so.. Please help me wih this. as it sounds I am a lot unexperienced beginning to be a beginner :)
