The read length graph shows the total number of bases vs the read length. The longest 1% of strands are classified as outliers, and excluded to allow focus on the main body of data.

The longest 1% of strands are classified as outliers, and aggregated into groups to show their relative amounts.

The cumulative output shows the total amount of bases or reads sequenced over time by your device.
Bases
Legend
Estimated
Predicted total number of bases, prior to basecalling
Passed
Bases equal to or above the quality score threshold.
Failed
Bases below the quality score threshold.
Reads
Legend
Total
Total number of reads, including passed, failed and skipped.
Passed
Reads equal to or above the quality score threshold.
Failed
Reads below the quality score threshold.
Skipped
Reads that will not be basecalled. Post run basecalling is possible.
The quality score is calculated as basecalling is performed on your device. Quality score is measured on the logarithmic PHRED scale. Reads that fall below the minimum value of 9 will be classified as failed reads. You can alter the accepted minimum quality score in MinKNOW.
Legend
Mode
The most frequent quality score of reads in the run.
Spread
The spread of quality scores, found by calculating full width half maximum.
Min. quality score
Minimum quality score to be accepted as a passed read.
Quality score low
This can be due to the translocation speed being out of the accepted range, check the translocation speed graph on this report. If the translocation speed is in the accepted range, please see the user guide for more info.
The Pore activity graph shows the performance of your sample as it is being sequenced during a run.

General
Some commonly seen issues are excess pores classified as Recovering, Open Pore, or Free Adapter. To find out what advice is applicable for your run, visit the user guide.
A Pore scan is performed at configurable time intervals to determine the current status of pores within channels on a Flow Cell. For this run a Pore scan is performed every 1.5hrs.
Legend
Active wells
Wells available for sequencing
Inactive wells
Wells unavailable for sequencing
High proportion Unavailable
Possible contaminants in library blocking the pore. Consider using the Flow Cell Wash Kit, and reloading a library.
High proportion Inactive
If localised to one area of the Flow Cell, this could indicate that an air bubble has been introduced during the flushing/loading steps. If inactivity is spread across the Flow Cell this could be caused by improper loading of the library, please refer to the user guide for further support.
The translocation speed is the rate at which DNA/RNA travels through pores as it is being sequenced.
Legend
Median
75% quartile
25% quartile
Accepted range
Low speed
Check that the Flow Cell is within the target temperature range.
The temperature of the Flow Cell over the run time.
Legend
Measured
Target
Out of range
Check that the Flow Cell is correctly seated and firmly pushed down into the device. Ensure ambient temperature is always within the specified range for your device in the user guide.
