Getting Started

2 Getting Started

To start the program, double click the MCE icon in the Neuromag folder of the Application manager. An iconified Matlab console appears on the desktop; do not close it! Also the main window shown in Figure 1 opens.

If you are using a previously calculated response, you should now load an old calculation (p. 12). Otherwise, you should select a data file using the [File] but- ton and select the head model (p. 8). The main window is described in more detail on page 22.

2.1 Analyzing data

To analyze your data with the L1 MNE, first you should calculate the estimates:

1.Load and pre-process the MEG data (p. 4)

2.Select the head model (p. 8)

3.Start the calculation (p. 11)

After you have loaded (p. 12) the calculated estimates, you can proceed by viewing the results (p. 33) at different times (p. 13) or by studying the temporal activity of the Regions of Interest (p. 14).

2.2 Quitting the program

You can quit the program by three alternative ways:

1.pressing the [Quit] button in the Main window

2.typing “quit” Matlab command in the terminal window

3.by closing the main window.
