Cluster Information

Selecting a cluster from your search results generates the following view

  • TOP LEFT
    A brief summary of the cluster indicating its index number, the number and types of sequences belonging to the cluster, the number of contigs predicted for the cluster by the assembly program (usually cap3 is used to generate cluster assembly's, however when cap3 fails, phrap is used)and the libraries represented by the cluster. For sequence types :
    • Blue = EST
    • Red = cDNA
    • Magenta = genomic DNA
    • Green = GSS

  • TOP RIGHT
    To the right of the summary table is the precomputed blast information available on the cluster. By moving the mouse over the appropriate button, different hits will be displayed within the text window (NB This only works for some browsers e..g Netscape 6). Clicking on the buttons launches a new window showing the BLAST output. It should be noted that similarity scores > e^-99 are scored as 0, "no significant hits " indicates that no hits with a similarity score of < e^-5 were obtained and 'no hits' indicate that no blast hits were found for this cluster.

  • MIDDLE
    Below the header information is data pertaining to each contig - the contig number, length of the sequence, number of ESTs which make up this particular contig and a list of these ESTs (coloured by type - see above). Click on the EST name to retreive the genbank entry.

  • BOTTOM
    Under the contig information is a simple graphic indicating the position of the sequences relative to the contig. The sequences are coloured according to quality/alignment information. Gold indicates sequence of high quality; purple indicates lower quality sequence used in creating the consensus sequence. Genbank entries can again be retreived by clicking on each sequence within the graphic. You can also view the alignment used for assembly of the cluster by clicking on the consensus (red box). Finally, below the graphic the cluster consensus sequence is given. The Blast button below this takes you to our in-house BLAST server automatically pasting in the consensus sequence
