+**Reference:** C. Soderlund (2019) Transcriptome computational workbench (TCW): analysis of single and comparative transcriptomes. Published at [BioRxiv](https://www.biorxiv.org/content/10.1101/733311v1).
 
-Description: For single-transcriptome (singleTCW) - similarity search against annotation databases, GO annotation, ORF finding and differential analysis. For multi-transcriptome (multiTCW) - compute similar pairs, provide statistics for pairs, compute clusters, provide statistics for clusters. Both singleTCW and multiTCW provide graphical interfaces for extensive query and display of the results.

-Requirements: Java and MySQL to build the database and view the results.  R for differential analysis.  The BLAST executable is necessary. The KaKs_Calculator is optional for the multi-transcriptome analysis. All other external software used by TCW is contained in the package tar file.
