Species diversity estimation for environmental samples. LSH-Div algorithm produces different diversity estimates such as Number of OTUs, Chao1 Index and ACE Index. Results are obtained at several distance cut-offs for eight environmental samples. The parameter setting used by LSH-Div algorithm to get these results is k = 30, w-mer = 3. Mothur and DOTUR are not able to process FS312 and FS319 samples due to large number of sequences and memory limitations.
