Have a question! Is EEGlab based on the 10-20 system? I didn't see the T3 point. I'm using the default file for training. Another question. I plan to use it for my Ph.D. Do I need to make any payment or obtain a usage license?
EEGLAB is not based on the 10-20 system but handles 10-20 channel data. If T3 is not present, then it might mean that it was not collected. You can use the EEGLAB compiled version for free without any license.
Hi, I have a question for the plotted channel properties for continuous data. As said at 3:40, "we stack the data for this channel, so that to see the whole activity throughout the session". I'm still not sure what does that mean? Initially, I guess that EEGLAB split the whole range of the continuous data into separate "epochs", then stack them. However, I plotted channel properties of my own continuous data which lasts for around 300s, the x-axis ranges around 300s (not frames as shown here), i.e., it's whole time range instead of "epoched clips", and the y-axis, as consistent with what was shown here, "Trials 100". We know that for continuous data, there is one single epoch without so-called trials. So in one word, what each horizontal bar is represented in channel properties plot for continuous data? Appreciate if who can answer my naïve question.
The image allows showing the entirety of the continuous data. The data is always divided into 100 chunks, and each chunk is color-coded and stacked on top of each other to be visualized.
If you remove let say, the following channels E48, E49, E60 re-run the spectra and maps plotting and find that one trace is very different click on the trace and it says channel 120 on the command line. When you go to Edit -> select data to remove this channel 120, is it referencing the actual channel (E120) or is it displaying the index? Since we removed 3 channels before it would have shifted...
It is showing the index. When you go to the menu to reject channels, you will see both the index and the channel labels so rejecting by index is as easy as rejecting by channel label.

Can I use this interface with my own circuit?
Dear Arnaud Delorme please help me how to add Automated artifact rejection tool to EEGLAB 2022.1
This option is hidden in EEGLAB version 2019 and later. You need to go into the preferences and click the button to show all menu items.
Hi, is there a possibility to edit channels automatically removed from clean_rawdata?
Removed channels should be saved in EEG.chaninfo.nodatchans
How do I only remove segments of a single channel as mentioned at 3:55 ?
You cannot do that. You could try interpolating the data for that channel using a custom script.
@@arnodelorme Ok, then I spend no more time searching for it ;) Thank you for the quick response and suggestion.

Yes, it is using index not labels.
i didnt found (Automatic channel rejection option on same dataset)
Hi, I am also facing the same problem. Did you get the solution?
@@eunsikkim8745 the function that's used is pop_rejchan(EEG). After I used it for the first time, the button appeared in EEGLab

@@arnodelorme thank you so much. It worked for me
I need to seperate my data to channels
Very informative, thanks
