The Viral mRNA track shows alignments between viral mRNAs in GenBank and the SARS genome.
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 genome using the blastz program. When a single mRNA aligned in multiple places, the alignment having the highest base identity was found. Only those alignments having at least 60% base identity were kept.
This track was produced at UCSC from mRNA sequence data submitted to the international public sequence databases by scientists worldwide.
