[Eeglablist] does electrode order have to be same across SS at study level?

[Arnaud Delorme]

Dear Agatha,

the order of the electrode does not need to be the same. EEGLAB was programmed to handle different channel orders. This said, for consistency and reliability, I would advise you to use the same electrode order.
We will revise the warning message to make it more informative.

Best regards,

Arno

If the electrode order needs to be the same... is there a tool out there that can be used to reorganize electrodes (e.g., alphabetically) If there is no tool - can you tell me whether there are any other fields other than .chaninfo/.chanlocs and obviously .data that need to be corrected?
