Mapping Statistics

This plot shows the fractions of correctly, wrongly and not mapped reads for each mapper and the selected mapping quality cutoff. Reads that have been filtered using the mapping quality cutoff are shown as unmapped. The interactive legend can be used to, for example, display only the number of wrongly and not mapped reads.

Edit Distance

This plot shows the effect of the number of mismatches introduced in reads on mapping rates.

Mapping Quality

This section represents an overview of the distribution of mapping quality values for all mappers. A detailed evaluation of mapping qualities for specific mappers can be found on the respective mapper results page (accessible using the navigation on top). The first plot rates each mapping quality threshold (0-255) by comparing the numbers of wrongly and correctly mapped reads that would be removed due to falling under the threshold. The second plot shows the total number of mapped reads for each mapping quality threshold (all reads with a mapping quality value smaller or equal to the threshold).
