Figure Lengend Snippet: 1. CloVR-16S supports analysis of pyrotagged amplicon pool sequence data as well as individual samples sequence data, using components from the Mothur package for preprocessing, alignment, operational taxonomic unit (OTU) assignment and alpha diversity estimation. QIIME components are used for sequence clustering, alignment, phylogenetic inference and beta diversity estimation. Sequence reads are assigned to taxonomies using the RDP classifier . Additional visualizations are generated with R script implemented in CloVR. Differentially abundant taxa determined with Metastats . 2. CloVR-Metagenomics supports functional and taxonomic assignments of non-redundant whole-genome shotgun (WGS) sequence data from metagenomic samples. Reads are classified based on BLASTX and BLASTN searches against functional (COG , optionally KEGG , eggNOG ) and taxonomic (RefSeq ) reference databases, respectively. The results are statistically evaluated using Metastats and visualized using R scripts implemented in CloVR. 3. CloVR-Microbe supports microbial whole-genome sequencing projects, including Illumina and 454 or Sanger sequence assembly with Velvet and Celera assembler (CA) , respectively. Gene predictions and annotations are performed using the complex IGS standard operating procedure for automated prokaryotic annotation (IGS) .
Article Snippet: CloVR supports a broad variety of small to large-scale microbial genomics applications of current and next-generation sequencing platforms with four automated pipelines: (i) 16S rRNA-based microbial community composition analysis of Sanger and 454 sequence data (CloVR-16S) ; (ii) taxonomic and functional community composition analysis of metagenomic whole-genome shotgun (WGS) sequence data (CloVR-Metagenomics) ; (iii) bacterial single-genome WGS Sanger, 454 or Illumina sequence assembly and annotation using the IGS Annotation Engine (CloVR-Microbe) ; and (iv) large-scale BLAST searches of Sanger, 454 or Illumina sequence data (CloVR-Search).
