Herein, we describe a software package, search, trim, identify, track, and capture the uniqueness of 16S rRNAs using public and in-house database (STITCH), which offers automated sequence pair splicing and genetic identification, thus simplifying the computationally intensive analysis of large sequencing libraries.
In particular, the approach presents two computational challenges: (1) the assembly of a composite sequence from the two partial reads and (2) the subsequent appropriate identification of the organism represented by the newly sequenced clones.

The sequencing process typically utilizes a forward and reverse primer pair to produce two partial reads (~700 to 800 base pairs each) that overlap and in total cover a large region of the full 16S rRNA sequence (~1.5 generates very large numbers of 16S rRNA datasets that can overwhelm manual processing efforts leading to both delays and errors. In environmental studies, polymerase chain reaction amplification of 16S rRNA followed by cloning and sequencing of numerous individual clones is an extensively used molecular method for elucidating microbial diversity. A comparison of variable regions within the 16S rRNA gene is widely used to characterize relationships between bacteria and to identify phylogenetic affiliation of unknown bacteria.
