Abstract:
cTrans is a comprehensive utility used to generate polypeptide databases from cDNA sequences. The goal is achieved through integrating four main functions, including retrieving sequences of species of interest from the downloaded packages from dbEST of GenBank, format conversion, checking and deleting vector and adaptor contamination, and translating the cDNA sequences in all six frames and selecting specific translations for database construction in a user-defined length threshold. In addition, this utility is also applicable to cDNA sequences produced by users themselves.
