Note: Before running a new heliOS version, a firmware update of your heliX or heliXcyto device is necessary.


With the new firmware update the fluidics control of your heliX biosensor will be improved which leads to better sample injections.

Note: After the update, the first priming/wake up & prime is used to calibrate the system automatically in order to activate the improved fluidics control. This may take up to 1 hour.


Please prepare the system and follow the instructions as described below:

  • Update your system as described in the install instructions.
  • Open heliOS 2023.2 and connect to your updated heliX instrument.
  • Run a Clean & Sleep (skip this step if the instrument is already in sleeping mode).
  • After the Clean & Sleep, connect at least 250 mL buffer to buffer tubes 1 and 3, respectively.
  • Make sure that the water vial at sample tray position A is filled with fresh deionized water (10 mL).
  • Place a Maintenance Chip into the chip tray at position 5.
  • Insert the chip and the sample tray.
  • Run a Wake Up & Prime. This may take up to 1 h untill the system is fully calibrated.
  • Wait until the run has finished. Now the instrument is calibrated and ready to be used again.

We are excited to announce a significant update to our Real-Time Interaction Cytometry (RT-IC) analyses and several other powerful enhancements to improve data analysis and interpretation.

RT-IC Analyses

In this update, we have focused on enhancing the visualization capabilities of RT-IC analyses. The color scheme in all plots has been refined, resulting in a more intuitive representation of data. Researchers can now easily identify patterns and anomalies, gaining valuable insights at a glance.

Additionally, we have simplified the analysis pipeline to reduce complexity without compromising detailed analysis capabilities. This streamlined process enables researchers to perform in-depth analysis and derive meaningful results more efficiently.

New Operation: Outlier Removal

We are thrilled to introduce a new mathematical operation specifically designed to remove outliers from raw measurement data. This operation automatically identifies and masks outliers using an intelligent algorithm. Researchers also have the flexibility to manually mask or unmask data points as needed, providing greater control over the analysis process.

By efficiently distinguishing valid measurements from anomalies, this operation ensures improved data quality. It saves time with automated outlier detection and empowers researchers to make necessary adjustments based on domain expertise or additional information.

Improved Usability for Point Selection Operations

Our artifact removal operations, including Mask Points and Jump Removal, have been significantly enhanced to simplify the process of removing measurement artifacts. With the introduction of a dedicated plot for artifact removal, researchers can now utilize specialized point markers to easily identify and remove artifacts.

This advanced point selection feature ensures precise artifact removal, improving the accuracy and efficiency of data cleaning. Researchers can now seamlessly identify and eliminate measurement artifacts, resulting in more reliable analysis outcomes.

New Residual Plots when plotting Fit Results

We are pleased to introduce a new feature that enhances fit analysis. In this release, we have included a supplementary residuals plot alongside every fit plot. This residuals plot visually displays discrepancies between the fitted model and the actual data, providing researchers with a comprehensive assessment of fit quality.

By observing the deviations between the fit curve and data points, researchers can gain deeper insights into the accuracy of the fit models. The residuals plot is automatically included with fit plots, and users have the option to hide it if desired. This addition allows for more informed judgments and improved fit analysis.


Navigation: Read-Mode and Edit-Mode

We are excited to introduce a new feature that offers enhanced flexibility and control over the documents in our scientific software. Method, Assay, and Analysis documents can now be viewed in read-mode or edited in edit-mode.

In read-mode, these documents can be securely accessed in a read-only format, ensuring data integrity and preventing accidental changes. Switching to edit-mode enables researchers to make deliberate modifications to the documents as needed.

For added convenience, users can configure their documents to open in read-mode by default, minimizing the risk of accidental modifications and providing an added layer of change protection.


Upgrade now to experience these enhancements and enjoy improved data visualization, simplified analysis pipelines, streamlined artifact removal, enhanced fit analysis with residuals plots, and flexible document viewing and editing modes. These updates empower researchers to interpret and analyze results confidently and efficiently, facilitating valuable scientific discoveries.

          We recommend to always use the newest versions of heliOS and heliX firmware.
          Please update first your heliX device with the latest firmware version before installing a new version of heliOS.


          Supported Operating System I Windows 10 and higher

          heliOS requires the .NET 6 Desktop Runtime.
          heliOS requires access to a postgreSQL database.

          heliX FIRMWARE UPDATE

          Note: The installation of a new heliX firmware version must be performed from a computer which is connected to the heliX device.

          Note: Skip this step if you are only interested in updating the heliOS version on a computer which is not used to control the heliX device.

          1. Ensure that the heliX device is switched on and connected to the control PC (directly or via network).
          2. Download the above listed version of the heliX firmware. We recommend to always use the newest version.
          3. Run the EXE installer on the control PC and follow the setup steps. You can find the IP address of your heliX in heliOS under Devices.
            After approx. 10 minutes the heliX will be restarted and ready to use.

          INSTALLATION OF heliOS

          Note: If heliOS is installed for the first time on a computer you need to first install the .NET 6 Desktop Runtime (see Installation of Microsoft .NET 6) and a PostgreSQL database (see Installation and setup of postgreSQL database).


          1. Download the above listed version of heliOS. We recommend to always use the newest version.
          2. Run the MSI installer and follow the setup steps.
          3. The first time you open heliOS on a computer you need to enter your license key (Settings → License).
            Copy and paste the license key into the intended input field and confirm.
          4. In addition to 3, the first time you are using heliOS you need to enter your database access data (Settings → Database).
          5. Now heliOS is ready to use and can, for example, be connected to your heliX device.

          IMPORT OF heliOS METHODS

          1. Download the above listed heliOS methods.
          2. Unzip the downloaded file once. The unzipped folder contains a range of zipped heliOS methods. Do not unzip these files.
          3. Open heliOS and go to “Methods”.
          4. Click on “Import” in the top menu and select one or several heliOS methods (ZIP files) from the unzipped folder.
          5. Click on “Open”. Now your data base is equipped with the newest heliOS methods.


          Note: heliOS requires the .NET 6 Desktop Runtime on your Windows operating system. If already installed you can skip this step.


          1. Download the .NET 6 Desktop Runtime installation file (64-bit version).
          2. Run the EXE installer and follow the setup steps.
          3. After the installation process has finished you are ready to install heliOS.
