Ieeg data format question

Discussions
1

I have a subject that completed a 48-hour ambulatory eeg and we would like to import the EEG data (approx 1.8GB) for review. The file format is .ieeg, which I am unfamiliar with. Is there a way to convert this data into a format compatible with Brainstorm?

Thanks,

I Matt,

I have never seen this extension. Do you know which EEG system and acquisition software created it?
Which software are you using to load it? Can you load it in any other open source software, such as EEGLAB?
Could you contact the manufacturer/seller of the EEG system to ask if they provide functions or libraries to load the files in Matlab?

Many EEG manufacturers do not let people read their file formats easily, and chose instead to add options to export their files to other standard formats, eg. EDF. You’d be able to import such files in Brainstorm easily.

Thanks Francois, I was able to export to EDF and now can see them.
