Metric
Description
Cycles
The number of cycles in the read.
Yield
The number of bases sequenced, which is updated as the run progresses.
Projected Yield
The projected number of bases expected to be sequenced at the end of the run.
Aligned
The percentage of the sample that aligned to the PhiX genome, which is determined for each level or read independently.
Error Rate
The calculated error rate of the reads that aligned to PhiX.
Intensity Cycle 1
The average of the A channel intensity measured at the first cycle averaged over filtered clusters. For the NextSeq 500 System, the red channel is used.
%Q ≥ 30
The percentage of bases with a quality score of 30 or higher, respectively. This chart is generated after the 25th cycle, and the values represent the current cycle.
Metric
Description
Clusters PF
The percentage of clusters passing filtering, +/- 1 standard deviation.
%Q ≥ 30
The percentage of bases with a quality score of 30 or higher, respectively. This chart is generated after the 25th cycle, and the values represent the current cycle.
Yield
The number of bases sequenced which passed filter.
Tiles
The number of tiles per lane.
Error Rate
The calculated error rate, as determined by the PhiX alignment. Select Subsequent columns display the error rate for cycles 1–35, 1–75, and 1–100.
Error Rate @cycle
The error rate for cycles 1–35, 1–75, and 1–100. Select the Error Rate value to view this metric.
Cycles Err Rated
The number of cycles that have been error-rated using PhiX, starting at cycle 1. Select the Error Rate value to view this metric.

The percentage that aligned to the PhiX genome. Select the Error Rate value to view this metric.
Reads PF
The number of clusters (in millions) passing filtering.
Total Reads
The number of clusters (in millions). Select the Reads PF value to view this metric.
Density
The density of clusters (in thousands per mm2) detected by image analysis, +/- 1 standard deviation.
Phas./Prephas.
The value used by RTA for the percentage of molecules in a cluster for which sequencing falls behind (phasing) or jumps ahead (prephasing) the current cycle within a read. For MiSeq and NextSeq, RTA generates phasing and prephasing estimates empirically for every cycle. The value displayed here is therefore not used in the actual phasing/prephasing calculations, but is an aggregate value determined from the first 25 cycles. For most applications, the value reported is very close to the value that is applied. For low diversity samples or samples with unbalanced base composition, the reported value can diverge from the values being applied because the value changes from cycle to cycle.
Phasing Slope/Offset, Prephasing Slope/Offset
The best-fit slope and offset of the phasing/prephasing corrections, calculated from the entire read.
Intensity
The average of the A channel intensity measured at the first cycle averaged over filtered clusters.
Status

The Charts tab displays graphs of run metrics that update as the run progresses. Use these charts to monitor the quality of the run.
Data by Cycle graphs the progression by cycle of quality metrics during a run.
The Data by Cycle chart has the following features:
You can select the displayed metric, surface (if your system scans multiple surfaces), cycle, and channel (base) using the drop-down lists.
The chart is displayed with tailored scaling by default, or you can fix the Y-axis scale by selecting the Fix Scale checkbox.
Some metrics (% ≥Q20 and % ≥Q30) are monitored for a single cycle by default, or you can monitor the cumulative metrics (up to that cycle) by selecting the Accum checkbox.
You can focus on an area of interest by dragging to pan the view or using the mouse wheel to zoom in.
The following table details the possible metrics displayed in this chart. The available options vary by run.
Q-Score Distribution graphs the number of bases by quality score. The quality score is cumulative for the current cycle. Only bases from reads that pass the quality filter are included.
Use it to evaluate the Q-Score distribution for a run, which is an excellent indicator for run performance.
The Q-Score Distribution chart has the following features:
You can select the displayed read and cycle using the drop-down lists.

The Flow Cell Chart shows color-coded quality metrics per tile for the entire flow cell.
Use the Flow Cell Chart to judge local differences per cycle, per lane, or per read in sequencing metrics on a flow cell. It is also an easy way to see the %≥Q30 metric, which is an excellent single metric to evaluate a run. Do not use the Flow Cell Chart to look at downstream analysis metrics.
The Flow Cell chart has the following features:
You can select the displayed metric, surface (if your system scans multiple surfaces), cycle, and channel (base) using the drop-down lists.
The color bar to the right of the chart indicates the values that the colors represent.
The chart is displayed with tailored scaling by default, or you can fix the Y-axis scale by selecting the Fix Scale checkbox.
Some metrics (% ≥Q20 and % ≥Q30) are monitored for a single cycle by default, or you can monitor the cumulative metrics (up to that cycle) by selecting the Accum checkbox.
Tiles that have not been measured or are not monitored are gray.
You can focus on an area of interest by dragging to pan the view or using the mouse wheel to zoom in.
The following table details the possible metrics displayed in this chart. The available options vary by run.
Note the variable scales used on these different parameters.
The Data by Lane chart plots allow you to view quality metrics per lane.
Use the Data By Lane plot to examine the difference in quality metrics between lanes. Do not use the Data By Lane plot to look at alignment or variant calling analysis metrics.
The Data by Lane plot has the following features:
You can select the metric, surface, and read from the drop-down lists.
The plots show the distribution of mean values for a given parameter across all tiles in a given lane.
The red line indicates the median tile value for the parameter displayed. Blue boxes are for raw clusters, green boxes for clusters passing filter.
The box outlines the interquartile range (the middle 50% of the data) for the tiles analyzed for the data point.
The error bars delineate the minimum and maximum without outliers.
The outliers are the values that are more than 1.5 times the interquartile range below the 25th percentile, or more than 1.5 times the interquartile range above the 75th percentile. Outliers are indicated as dots.
You can focus on an area of interest by dragging to pan the view or using the mouse wheel to zoom in.
