Distribution-based OTU calling
dbotu3 is a new implementation of Sarah Preheim’s dbOTU algorithm. The scope is narrower, the numerical comparisons are faster, and the interface is more user-friendly.
Read the documentation for:
- a guide to getting started,
- an explanation of the algorithm, and
- the API reference.
dbotu3 is on PyPi and can be installed with pip.
- 1.1: Corrected error where sequence IDs that could be read as integers would not be found in the table
- 1.2: Python 2 compatibility, tox test framework, warnings for improperly-formatted sequence count tables
- 1.2.1: Added setup requirements
- 1.3.0: Improved OTU file header. Split the log file into a debug and progress log.
- 1.4.0: Made an improvement to the Levenshtein-based genetic dissimilarity metric.
- 1.4.1: Account for pandas API change to MultiIndex
- 1.5.0: Added the restart and rep seq scripts
- 1.5.1: New function for Qiime2 compatibility
- Testing for the restart scripts
- Better coverage for unit tests
