General questions

  • We don’t have the agreement for clinical use yet. If you are also a researcher, you can explore Halyzia under research purpose only.

  • We offer an onboarding session training at the beginning of your journey. You can also reach out to our support team from Monday to Friday between 9-5 pm at support_halyzia@avriomedtech.com

    You can find relevant information on the user’s manual.

  • Halyzia is compatible with .ncs, .nsX, .med, .trc, .edf, files formats. The nsX format starts from 3 to 7 and is related to the sampling frequency, 3 is the lower frequency.

  • You can contact our support team at support_halyzia@avriomedtech.com .

    In order to facilitate the process, please provide as much context as possible (screenshots, implantation file, ...). We are super responsive to answer!

  • Absolutely not. We cannot see your work or neither have access to your data, the raw data or your patients’ folders. We do anonymize all the folders opened in Halyzia.

Regarding the product

  • You need to download the Halyzia’s exe and make sure the folder is complete. Then you can unzip it. And directly launch the app.

    You may encounter some firewall issue, but not necessarily. If so, you need to allow anyway the application to run on your computer, it is a safe application.

  • If you mark as bad a channels or multiple channels they won’t be detected. You can also hide them to remove them from the signal. But if you only Hide a channel, it will still be detected.

    Here are some details that are interesting to know when switching from bipolar or monopolar:

    • In monopolar mode

     You can hide and mark as bad one or more channels, this remains recorded.

    Mark as bad channels will also be recorded in bipolar mode.

    Hide channels are only recorded in monopolar mode; this does not communicate with other modes.

    You can hide and mark as bad a macro or micro channel.

    • In bipolar mode

    You cannot mark as bad one or more channels.

    You can hide a micro or macro channel, but this does not communicate with the change of mode.

    Hide channels are recorded according to the mode in which they are made.

  • The edit implantation feature is here to help you setup your electrodes easily. This editor treats only macro electrodes, and the setup is mirrored in the topographic map.

    You can select electrodes and drawn them out of the windows to remove them. You can go to “show electrodes” to select electrodes you may wish to add.

  • From the main viewer, you can display a single channel by doing a right click mouse on the specific channel and select “Hide other” on the menu that is displayed.

  • We advise you to use the monopolar mode to explore and clean your signal. It is the best way to “Mark as bad” a channels or multiple channels, to Hide them.

    We recommend launching the detection in bipolar montage. You can’t modify the montage once a detection is launched.

About the detectors

  • You should launch a detection in bipolar mode, you cannot cancel a detection, and you can still do you work on the signal while the detection is active. You can analyse an event as soon as it has been detected and label it. You can navigate in your signal.

  • For a one hour signal you can expect 45 min to detect Fast Ripple and Ripples and about 30 min to detect epileptic spikes.

  • Yes, they are saved once they are detected.

  • Yes, you can. Also, once detected, the events are saved. You can launch a detection where you end the last one.

  • You cannot stop a detection in progress, but you can close you session in “File < Close” and reopen your session, the detection will be stopped. If some events have been detected they will be saved. If you don’t want to save those events, you should create a new folder with the same raw data to restart.

The topographic map & the metrics

  • Not yet, you can print screen your topographic map.

  • Most active electrode: this panel shows the temporal distribution of spikes over the entire recording, as a function of the amplitude of the filtered signal (N1-P2) for the electrode that has the highest number of detected events.

    All electrodes: This panel shows the temporal distribution of spikes over the entire record-ing, as a function of the amplitude of the filtered signal (N1-P2) for all events at all elec-trodes. Each color indicates a specific electrode.

  • Indeed, each time you are launching a detection, you can generate a topographic map.

    You have one topographic map per detection. So each topographic map is related to a specific montage too.

  • You can export details on the vents detected for each type of biomarker, they are on an excel file format.
