What is TardiBASE ? A database resource currently being developed by Mark Blaxter, University of Edinburgh. Provides a simple easy-to-use access point to the publically available tardigrade Hypsibius dujardini sequence and functional data. Searching TardiBASE Cluster information can be retrieved from TardiBASE using A specific cluster ID or Genbank accesion number for a sequence of interest Simple text queries on precomputed blast annotations. Sequence similarity by searching the H.dujardini cluster sequences Library specific searching is currently being developed. TardiBASE output TardiBASE provides lists of sequence clusters which fulfill the search criteria. Information on individual clusters include : library expression, consensus build, precomputed blast results, sequence trace view predicted proten translation:- size, molecular weight, pI, putative location, residue composition, domain identification. A novel phylogenetics tool (SimiTri) which enables a visual comparison of the phylogenetic relationships of individual clusters has been developed for NemBASE and we are working to incorporate this feature into TardiBASE.
