We've been hard at work to bring new functionality to your laboratory. Genotyper 3.1 resolves some bugs, improves user experience across the board and includes other general improvements.
As always, let us know what you think.
New features in Genotyper 3.1
Visualize passive reference dye intensity (ROX-view)
A passive reference dye (PRD) is used to normalize pipetting variance in your liquid handling equipment. Using a dye that always returns a fluorescence value, we can offset any pipetting variance by normalizing our main fluorescent signals (often, FAM & VIC).
Before 3.1, we visualized shortfall samples (i.e. a passive reference dye signal below a given threshold). With our newest release, we're giving you more granular control of the data.
Our new passive reference dye view allows you to analyze pipetting artefacts right on the plateview. Click on the PRD icon on top of the plate view. Both the plate- and plot-view will change datapoint colors. Switch back via the
icon.
All PRD values in the plate are ranked from low to high and visualized with a light to dark color. Hover over each well to see the exact fluorescence values (only in the plate view, not in the plot view).
If datapoints on the plates are detected as being a shortfall, this is when the PRD-value < instrument threshold, a label will be visualized on the PRD-icon.
‘Fail’ or ‘Do not export’ a PCR plate
Failing and not exporting on a PCR plate level is now possible for all users (even non-Kraken ones). With this new feature, you can choose to fail one or more PCR plates or exclude the results from the export file completely.
Use the dropdown in the plate table for 1 plate:
Next to that, you can also do it at the level of all plates, simply use the dropdown in the upper right corner of the screen for one or multiple selected plates:
These options are now available:
Export is the default selection and will export the call for all datapoints as expected.
Export as failed will mark the result for all datapoints on this plate as ‘Failed’.
Genotyper will enforce you to submit a reason for failure. The default reasons can be adjusted in Settings > General > Failed plate settings.

Spring cleaning our import and export settings, and adding more useful new export settings
We introduced many new settings to ensure the Genotyper export files (Universal and Grid export) fit into as many different laboratory workflows as possible.
The new settings available in 3.1 include:
Export data using the assay sorting that was used in imported files (grid, universal export)
Export empty wells that were explicitly imported (grid, universal export)
Export with customized column headers (grid, universal export)
Transpose markers and samples (grid export)
Export detailed calls: shortfall, inconclusive, bad, ... (grid export)
Assay sorting
A third option is introduced to sort your assays in the opened analysis view: sort by file order.
General improvements
Used history grid
In the past, reviewing historically made decisions in Genotyper could be confusing. When opening an authorized analysis, you would see the 'today' history. Obviously, that removed the important historic context in which the AI and users took decisions.
Going forward, we're storing the history grids upon authorization, and visualize them at the point-in-time of authorization. Giving you the possibility to see data exactly the way your team/ AI saw it when analyzing the data.
This is a first important step in providing more, granular Metrics data for assay quality, more news on that soon.
Lasso-tool & NTC
When a group of datapoints is selected with the lasso-tool, the manual override call will only affect the regular datapoints and the positive controls. NTCs will not be re-scored.
The result of an NTC can be edited by only selecting the NTC without any other datapoints.
This way, when a group of samples is rescored or unscored, uncalled NTCs (i.e. NTCs that passed) that lie within lassoed group will remain passed.
More reads available: from 5 to 7 reads
For input files with data of multiple reads, the number of reads analyzed by Genotyper is increased from 5 to 7. If more than 5 reads are available in your input file, you’ll notice the slider will now show up to 7 reads.
Customers using the Biomark (Fluidigm) instrument can now import the default multi-read file.
We are now only ~33 reads removed from giving you real-time PCR data.
Adding new file(s)
The ‘add new file(s)’ functionality is improved to support more types of data.
Add a new read (same PCR plate with same samples)
Add an extra plate (new PCR plate)

Remember assay filters
Same as in the filters in the Analysis overview page, the filters in the Assay module are now remembered.
Set a filter, click around in Genotyper and go back to the assay module. You’ll see your filters are still in place.

Bugfixes
Using filter ‘Last Modified By’ in the Analysis overview page used to give an error message. Even though this was not an error. We fixed it.
For analysis with multiple assays, the assay scrollbar would get weirdly out of position after scoring a datapoint. We have told it what to do now and it behaves accordingly.
User experience in case setting Plate Selection Behaviour is set to All Plates Selected is fixed . As soon as all plates are selected in an assay this has higher priority then individual plate selection.
