rrnDB Estimate

Estimate is an on-line interface to the RDP Classifier tool, including adjustment of relative abundance of taxons based on 16S gene copy number data from rrnDB. Estimate produces three output files; one for the sequence classifications and two hierarchy files containing the unadjusted and copy-number-adjusted relative abundance of taxons. The filename of the adjusted copy number data will be prefixed cnadjusted_.

The pan-taxa copy number statistics upon which this service is based are available in tab-delimited format on the rrnDB Download page.

Estimate runs RDP Classifier version 2.14 using 16S training set № 19 incorporating current rrnDB copy number data. The necessary training files were re-created following the documented use of RDP Classifier's train command, replacing the copy number file from the original training set with one derived from the most recent downloadable pan-taxa statistics.
