[Eeglablist] Gratton ocular correction issue

[Thang Le]

Hi everyone,

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.

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:

Number of EOG channel for regression: [65 66]
Channels: [1 64]
Window for Blink-detection: 24
Voltage for Blink-detection: 200

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.

Thank you so much for your help.

Le
