GUI v5 playback error: "Cannot instantiate underlying board..."

ScipioScipio Nigeria
edited August 2020 in OpenBCI_GUI

@wjcroft Hi!
Firstly, I have attempted to playback a selected pre-recorded file and failed, getting the following response on the OpenBCI GUI: 'Cannot instantiate underlying board of class OpenBCI_GUI$BoardCytonSerial'. Kindly suggest a solution to this problem.

Secondly, I would like to be referred to OpenBCI documentation that would help me interpret the EEG live data appearing on the OpenBCI panels: for example FFT, Head Plot and Time Series, etc.

    There is not enough information here to determine why this would happen. GUI v4 files will need to be converted to GUI v5 format.

  • retiututretiutut Louisiana, USA

    Please post a ConsoleLog file and/or share the file in question.

  • retiututretiutut Louisiana, USA

    The first 100 lines of a file is also enough to test.

    @retiutut The next time I open my computer, I will try to playback the file with the dongle inserted and powered on together with the Cyton. Maybe, that might work. If it doesn't, I will post the first 100 lines of the file. Not sure what a ConsoleLog file is. Thanks.

    @Scipio

    'Cannot instantiate underlying board of class OpenBCI_GUI$BoardCytonSerial'

    I will try to playback the file with the dongle inserted and powered on together with the Cyton.

    You do not have to have the Cyton dongle connected to view a playback file, the error message above means it was unable to make a GUI instance of the specific Board class in Java/Processing.

    The console log information can be accessed using the button in the top right of the GUI. Here is a picture to show:

    @Scipio Can you also share a console log file when you try to playback this file?

    I am not able to reproduce this issue. The file header and data you just shared is valid v5 format.

    @retiutut I have finally initiated a playback session with the following Console Log details:-
