Table 11 Summary tab—sequencing install run
Result Description
Install run
Install run status Pass or fail.
Install run passing criteria The number of capillaries that must pass the QV20CRL limit (described below). If
spectr
al borrowing is enabled, 22 capillaries must pass for 24-capillary instruments
and 7 capillaries must pass for 8-capillary instruments.
Per-capillary passing
criteria QV20 CRL
(contiguous read length)
limit
The longest uninterrupted segment of basecalls with an average Quality Value (QV)
≥20.
In addition to evaluating the QV of a basecall, the software considers the QV of
adjacent basecalls within a 21-bp moving window to determine a contiguous read
length based on quality values: the software starts from the 5' end and calculates the
average QV across a moving window size of 21, sliding 1 bp at a time, to the 3' end.
The resulting longest contiguous segment is determined as the CRL.
For QV20CRL limits, see “QV20 CRL limits—sequencing install run” on page 346.
# Caps passed and
# Caps failed
The number of capillaries that met or did not meet the QV20CRL limit.
# CRL mean and # CRL sd The QV20 mean and standard deviation for all capillaries in the injection.
