<font face="Default Sans Serif,Verdana,Arial,Helvetica,sans-serif">Hi everyone,<br><br>I
am running into a problem with the Gratton's ocular correction method
in EEGLAB and I was wondering whether you could help me troubleshoot. <br><br>I have been attempting to apply
the Gratton's ocular correction method to a 64-channel data set. The two
EOG channels are 65 and 66. So far I have downsampled the data to
256Hz, rereferenced and segmented. The values I used for Gratton's were: <br><br>Number of EOG channel for regression: [65 66]<br>Channels: [1 64]<br>Window for Blink-detection: 24<br>Voltage for Blink-detection: 200<br>
<br>However, EEGLAB would give me an error message that says "To RESHAPE the number
of elements must not change". I wasn't sure what to use for blink window but it does not look like 24 is the right value.<br><br>Thank you so much for your help.<br><br>Le<br></font>
