Right clicking on channel graph directly:

Resize – use mouse wheel or PgUp/PgDn to size graph vertically

Use default size – snaps selected graph back to default size

Move – mouse up and down to desired position, click to release graph

Add reference lines- Adds dotted reference lines above and below baseline. Dialog box allows you to select voltage, zero will remove lines

Change color – Dialog box to choose desired color

Hide – Hides channel

Align channel – spaces channels evenly along vertical axis

Duplicate – creates a duplicate of selected channel

Copy epoch to clipboard

Export channel to workspace – saves channel to workspace variable

Show PSD

Show MUSIC

Epoch statistics – shows table of median, mean, avg power, rms, variance, standard deviation, entropy

Changing scale of channel

Occasionally with some of the respiratory measurements (Chest, Abd, RIP-Sum), the units are in microvolts when the signal is clearly in the 0.1-10 V range. This results in a huge signal that stretches beyond the limits of the display window and even resizing will be inadequate. We will work on that.

In the meantime, here are a couple of solutions to this problem:

  1. Right-click on channel graph and "copy epoch to clipboard." In MATLAB command window, paste the epoch and set it to a variable like "x". Then you can plot x.

  2. This is the better solution. Go to the Filter Toolbox and select "filter_scale." Set scaling factor to .001. Then resize or use default scale.

Take screenshot:

Saves current main window display. Can choose target directory and choice of PNG or JPG.

Import

Imports Events from .SCO, .txt, container file (.evt), or database.

The Import event from .SCO option automatically selects the .SCO file corresponding to the loaded .EDF file, if you kept the default naming convention.

Export

Exports Events to .txt, container file (.evt), PSD or FFT to .txt.

Load channels

Loads additional channels after loading EDF
