[Eeglablist] extracting cluster specs for each subject

[Agatha Lenartowicz]

Hi all ~ I would like to extract the subject specific dat contributing to each cluster solution (from an MP clustering applied to ICs). Can you point me to the appropriate data structure or set of files where these live?

Many thanks
agatha

I mean, that I can see only the name of the event. Additional data (event fields) are not imported. Does anyone have an idea of how to attach this data do EEGLAB? I assume that this information is written in additional channels. But EEGLAB deletes all of these channels except one with the basic info.

These epochs are essential because of the experiment design (experiment is too long and we have to do breaks). When I export this data from NetStation as simple binary, this file is being broken into files representing epochs in original recording. I can import this bunch of files with pop_readsegegi command. This function does the job well, except one little bug: NetStation counts time from the beginning of the experiment. Pauses during the recording are treated as the beginning of epochs. In EEGLAB all epochs have continuous time, so there is no possibility to attach events exported from NetStation, because the time after the first epoch is different.
