The Reads Tab

3.7	The Reads Tab

3.7.1 Reads Tab Features and Functionalities

The Reads tab (Figure 37) provides statistics on the read length and read quality observed during the sequencing Run for either the sample library reads (sequencing key TCAG or GACT) or the Control DNA reads (sequencing key GACT, CATG or ATGC; see Section 7.1 for details). It displays a plot of the read length or quality data either for a selected PTP region or across the whole PTP Device, and a table of region-by-region and whole PTP Device statistics of related data.

Figure 37: The GS Run Browser application’s Reads tab, showing the number of wells producing final library reads over the entire PTP Device, and whose reads were determined by the data processing software as being of any given read length.

For the Reads tab data to be displayed, the region.cwf files (or, for the GS FLX standard chemistry, files 454QualityFilterMetrics.txt and 454BaseCallerMetrics.txt) must be present in the data processing directory of the selected Run.
