The document provides an introduction and tutorial on setting up Distributed Annotation System (DAS) tracks using VectorBase. DAS allows decentralized storage and integration of sequence annotations. The tutorial demonstrates uploading RNA-seq annotation data from Anopheles as a DAS track in VectorBase, including uploading a file or pasting tab-delimited data. It describes the DAS concept of multiple annotation servers storing different data types that can be viewed simultaneously by a client.
