| POP_EEGPLOT |
Visually inspect EEG data using a scrolling display. Perform rejection or marking for rejection of visually (and/or previously) selected data portions (i.e., stretches of continuous data or whole data epochs). |
 |
|
| Usage: |
>> pop_eegplot( EEG ) % Scroll EEG channel data. Allow marking for rejection via
% button 'Update Marks' but perform no actual data rejection.
% Do not show or use marks from previous visual inspections
% or from semi-auotmatic rejection.
>> pop_eegplot( EEG, typerej, superpose, reject ); |
|
| Graphic interface: |
"Add to previously marked rejections" |
[edit box] Either YES or NO. Command line equivalent: 'superpose'. |
"Reject marked trials" |
[edit box] Either YES or NO. Command line equivalent 'reject'. |
|
| Inputs: |

typerej |
type of rejection 0 = independent components; |
1 |
data channels. {Default: 1 = data channels} |
superpose |
0 = Show new marks only: Do not color the background of data portions previously marked for rejection by visual inspection. Mark new data portions for rejection by first coloring them (by dragging the left mouse button), finally pressing the 'Update Marks' or 'Reject' buttons (see 'reject' below). Previous markings from visual inspection will be lost. |

Show data portions previously marked by visual inspection plus data portions selected in this window for rejection (by dragging the left mouse button in this window). These are differentiated using a lighter and darker hue, respectively). Pressing the 'Update Marks' or 'Reject' buttons (see 'reject' below) will then mark or reject all the colored data portions. {Default: 0, show and act on new marks only} |
reject |
0 = Mark for rejection. Mark data portions by dragging the left mouse button on the data windows (producing a background coloring indicating the extent of the marked data portion). Then press the screen button 'Update Marks' to store the data portions marked for rejection (stretches of continuous data or whole data epochs). No 'Reject' button is present, so data marked for rejection cannot be actually rejected from this eegplot() window. |

Reject marked trials. After inspecting/selecting data portions for rejection, press button 'Reject' to reject (remove) them from the EEG dataset (i.e., those portions plottted on a colored background. {default: 0, mark for rejection only} |
|
| Outputs: |
Modifications are applied to the current EEG dataset at the end of the
eegplot() call, when the user presses the 'Update Marks' or 'Reject' button. |
|
| NOTE: |
The modifications made are not saved into EEGLAB history. As of v4.2,
events contained in rejected data portions are remembered in the EEG.urevent
structure (see EEGLAB tutorial). |
