The chimera.seqs command has been broken up into 7 separate commands.

Presently, mothur implements seven methods to determine if a sequence is chimeric. If there is an algorithm that you would like to see implemented, please consider either contributing to the mothur project or contacting the developers and we'll see what we can do. For this tutorial you should download the chimera files and decompress it.

  • chimera.bellerophon: ...
  • chimera.pintail: looks at the variation between the expected differences and the observed differences in the query sequence over several windows.
  • chimera.check: 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.
  • chimera.ccode: compares differences in distances, for each word, between query sequence and reference sequences, and reference sequences and themselves.
