| UCHIME is a new algorithm for detecting chimeric sequences. It was developed in |
| collaboration with Brian Haas, Jose Carlos Clemente, Chris Quince and Rob |
| Knight. Chimeras are commonly created during DNA sample amplification by |
| PCR, especially in community sequencing experiments using single regions |
| such as the 16S rRNA gene in bacteria or the fungal ITS region. UCHIME can |
| detect chimeras using a reference database or de novo using abundance |
| information on the assumption that chimeras are less abundant than their |
| parents because they must have undergone fewer rounds of amplification. |
