Papers and citing USEARCH
Algorithm | Description | |
USEARCH | Ultra-fast global alignment search for high-identity top hit or hits. | |
UCLUST | Ultra-fast general-purpose clustering. See also OTU clustering. | |
UBLAST | Fast, sensitive database search by local alignment. Similar to BLAST in some ways, but much faster due to the use of an index. | |
UPARSE-REF | Error inference by maximum parsimony. Used for annotating sequences obtained in mock community experiments. | |
UPARSE-OTU | OTU clustering of marker gene reads, e.g. 16S or ITS.. | |
UCHIME2 | Search for chimeric sequences. | |
Dereplication | Find unique sequences (delete duplicated sequences). | |
ORF detection | Identification of Open Reading Frames (ORFs) in nucleotide sequences. | |
Local clustering | Clustering using local alignments | |
Paired read merging | Merging (assembly) of paired reads. | |
UNOISE2 | Error-correction (denoising) of amplicon reads | |
UTAX | Taxonomy prediction for marker genes (16S, ITS...). Obsolete. | |
SINTAX | Taxonomy prediction for marker genes (16S, ITS...). | |
Read quality filtering | Quality filtering of reads with Phred (quality) scores.. | |
Masking | Detection of repetitive or low-complexity regions. | |
Demultiplexing | Assign reads to samples using index reads. | |
UNCROSS | Detect and filter cross-talk in a OTU table. | |
UNBIAS | Correct for amplification bias in an OTU table. |
