Related Software:

  • PattRun - A front-end and visualization program that provides a convenient interface for running Bayesian Decomposition and for viewing the results. The program allows the user to read tab-delimited files for data, uncertainty (optional), class membership (optional), and coregulation (optional), and produces output tab-delimited files if desired. The source code of PattRun is released under the GNU general public (GPL). PattRun is included in the PattTools directory when downloaded.
  • ClutrFree - A cluster viewer package available as a java Application. ClutrFree provides essentially the ability to compare microarray clusters issued from different experiments, i.e. the same algorithm used with different parameters or different algorithms. ClutrFree features a procedure to construct a tree from those clusters to infer which ones are more stable among different experiments. Also, ClutrFree displays genes and their memberships along with annotations and ontology. Source code, pre-compiled bytecode, documentation and test datasets are provided. The source code of ClutrFree is released under the GNU general public license (GPL).
