**Mothur Overview**

Mothur_, initiated by Dr. Patrick Schloss and his software development team
in the Department of Microbiology and Immunology at The University of Michigan,
provides bioinformatics for the microbial ecology community.

**Command Documenation**

The chimera.check_ command identifies putative chimeras using the chimeraCheck approach. It looks at distance of left side of query to it's closest match + distance of right side of query to it's closest match - distance of whole query and its closest match over several windows.  

Note: following the RDP model this method does not determine whether or not a sequence is chimeric, but allows you to determine that based on the IS values produced.
