Read

The sum of bases from passing filter clusters that are not N over all cycles, except the last cycle, scaled to the total read length, divided by 1E9 to put in units of gigabases. The scaling factor is defined, per lane, as the final number of entries (tiles in the lane x usable cycles) divided by the current number of entries for the read/lane in the QMetrics file.

Non-Indexed Total

The sum of the projected total yield over all reads, excluding indexed reads.
