New Sequence Quality Metrics in BaseSpace™ Sequence Hub

The Run Monitoring features in BaseSpaceTM Sequence Hub (BSSH) enable users to remotely monitor the quality of their sequencing runs and troubleshoot sequencing errors. As part of our efforts to extend real time Run Monitoring capabilities, we recently released new data quality metrics in BSSH.

 

% Occupancy for iSeq™ and MiniSeq™ instruments

 In a previous release, we added the %Occupied measure in the Charts section of Run Monitoring for the NovaSeq™ systems. As part of this release, this metric will now be visible for iSeq and MiniSeq systems, in BaseSpace Sequence Hub. This measure can be used to understand loading concentrations on the flow cell.

For patterned and non-patterned flow cells, % Occupancy is the percentage of clusters on the flowcell that have DNA that can ultimately be sequenced. With patterned flow cells (such as iSeq), the number of nano wells on the patterned grid determines the total number of possible clusters. For non-patterned flow cells (such as MiniSeq), the total number of possible clusters is the number of non-duplicated spots identified by Real Time Analysis (RTA) during template generation.

% Pass Filter (%PF) settings for all instruments

 The Flow Cell chart in BaseSpace Sequence Hub has also been updated to include the %Pass Filter (%PF) for all instruments. This additional information will allow users to determine in particular tiles of a flowcell have unusual levels of %PF.

With these enhancements, we have added capabilities that are currently not available in Sequence Analysis Viewer (SAV). SAV will be updated in the future so our users have a consistent experience across SAV and BSSH.
