Mapping result
Reads can be mapped to linear and circular chromosomes. Read mappings to circular genomes are visualized linearly as shown in figure 21.22.
Figure 21.22: Mapping reads to a circular chromosome. Reads that are marked with double arrows at the ends are reads that map across the starting point of the sequence. The arrows indicate that the alignment continues at the other end of the reference sequence.
Reads that map across the starting point of the sequence are shown both at the start and end of the reference sequence. Such reads are marked with » at the end of the read to indicate that the alignment continues at the other end of the reference sequence.
The result of the read mapping is a read mapping track (
).
Note: If your reads track shows the message 'Too much data for rendering' on a grey background, simply zoom in to see your reads in more detail. This occurs when there are too many reads (more than 500,000) to be displayed clearly.
