| POP_REJTREND | Measure linear trends in EEG data; reject data epochs containing strong trends. |
 | |
| Usage: | >> pop_rejtrend( INEEG, typerej); % pop up an interactive window >> OUTEEG = pop_rejtrend( INEEG, typerej, elec_comp, winsize, maxslope, minR, superpose, reject); |
| Pop-up window interface: | |
"Electrode|Component number(s)" |
[edit box] electrode or component number(s) to take into consideration during rejection. Sets the 'elec_comp' parameter in the command line call (see below). |
"Slope window width" |
[edit box] integer number of consecutive data points to use in detecting linear trends. Sets the 'winsize' parameter in the command line call. |
"Maximum slope to allow" |
[edit box] maximal absolute slope of the linear trend to allow in the data. If electrode data, uV/epoch; if component data, std. dev./epoch. Sets the 'maxslope' parameter in the command line call. "R-square limit" -[edit box] maximal regression R-square (0 to 1) value to allow. Sets the 'minR' parameter in the command line call. |
"Display previous rejection marks?" |
[edit box] either YES or NO. Sets the command line input option 'superpose'. |
"Reject marked trials?" |
[edit box] either YES or NO. Sets the command line input option 'reject'. |
| Command line inputs: | |
INEEG |
input EEG dataset |
typerej |
[1|0] data to reject on: 0 = component activations; |
1 |
electrode data. {Default: 1}. |
elec_comp |
[e1 e2 ...] electrode|component number(s) to take into consideration during rejection |
winsize |
(integer) number of consecutive points to use in detecing linear trends |
maxslope |
maximal absolute slope of the linear trend to allow in the data |
minR |
minimal linear regression R-square value to allow in the data (= coefficient of determination, between 0 and 1) |
superpose |
[0|1] 0 = Do not superpose marks on previous marks stored in the dataset; 1 = Show both types of marks using different colors. {Default: 0} |
reject |
[1|0] 0 = Do not reject marked trials but store the labels; 1 = Reject marked trials. {Default: 1} |
| Outputs: | |
OUTEEG |
output dataset with rejected trials marked for rejection |
| Note: | When eegplot() is called, modifications are applied to the current dataset at the end of the call to eegplot() (e.g., when the user presses the 'Reject' button). |
