Open your OpenSignals software to visualize signals.
Enter the OpenSignals Visualization Mode by clicking the play button in the main interface.
Click on the folder icon (1) in the OpenSignals visualization mode to open the file browser.
Navigate to the directory where your acquisition files are stored (2) and select the .TXT or .H5 acquisition file of your choice (2). Once selected, OpenSignals will display information about the acquisition setup on the right side of the file browser (this might not be visible for older acquisition files).
Open your file by clicking on the OK button (4).
The signals of your acquisition file will now be displayed in OpenSignals, where you can proceed with visualizating the segments of your choice, add annotations, or use the OpenSignals add-ons to process your sensor data.
