Importing MSNA data from Labchart into Ensemble

  • For recordings where the MSNA Burst signal is NOT a calculated channel

    1. Select data and save as chart file
    2. Import the Chart file to Ensemble
      1. Set ‘sampling frequency’ to the highest sampling frequency in your file (typically 10,000Hz for files containing MSNA)
      2. Select ‘Different sampling frequency’
      3. Set decimation = 40 (giving a 250Hz downsampled signal).
    3. Under Extra channels specify the MSNA BURST signal


  • For recordings where burst signal IS a calculated channel

    1. Check that channel calculations store 6 decimal places. The burst signal must store 6 decimal places to export properly
    2. Select data for analysis and export selection as .txt file
      1. Check current selection, clip values, block header, time, always seconds, comments, event markers
      2. downsample by 40 (if the original MSNA signal is 10,000Hz)
    3. Import the .txt file to Ensemble
      1. Set sampling frequency to 250Hz.
      2. Select ‘Same sampling frequency’
      3. Set decimation to 1
    4. Under Extra channels specify your MSNA BURST signal
