**Command Documentation**

The chimera.ccode_ command identifies putative chimeras using the ccode approach (Chimera and Cross-Over Detection and Evaluation).  Ccode_ compares differences in distances, for each word, between query sequence and reference sequences, and reference sequences and themselves.

This method was written using the algorithms described in the paper_ "Evaluating putative chimeric sequences from PCR-amplified products" by Juan M. Gonzalez, Johannes Zimmerman and Cesareo Saiz-Jimenez.

The program can analyze sequences for any required word length. Generally, values of 5-20% of sequence length appear to deliver accurate results, for example, working on 16S rDNA sequences with a full-length of #1500 nt. It should be noted that the use of fragments either too long or too short might result in a reduction of sensitivity.
