This track shows alignments between viral mRNAs in GenBank and the SARS draft sequence.
This track follows the display conventions for PSL alignment tracks. In dense display mode, the items that are more darkly shaded indicate matches of better quality.
The description page for this track has a filter that can be used to change the display mode, alter the color, and include/exclude a subset of items within the track. This may be helpful when many items are shown in the track display, especially when only some are relevant to the current task.
To use the filter:
GenBank viral mRNAs were aligned against the SARS draft sequence using the blat program (translated alignments). These alignments were not filtered (as they usually would be for vertebrate genomes) because of the rapid evolution of viruses and the greater variance.
This track was produced at UCSC from mRNA sequence data submitted to the international public sequence databases by scientists worldwide.
