Native Netstation files (new ones) cannot be imported. Only "Netstation binary simple" files can be imported in EEGLAB. EDF files can also be exported from Netstation and imported in EEGLAB, but the events are not stored in the last channel. Converting data files to "Netstation binary simple" is the simpliest way to get EGI files under EEGLAB/Matlab.

Message from Stephen Hamilton sthamilton at ucdavis.edu on the EEGLABLIST about his problem with events
In the end, we performed segmentation mark-up in Netstation before exporting the data files into .raw format. This was mostly straightforward, but we did have some problems reading accuracy information from the TRSP events (given by Netstation) into EEGlab, particularly when these events occurred at recording boundaries. No error messages came up, we just noticed that there weren't enough trials in each condition and then saw that some TRSP events did not contain accuracy evaluations. As a consequence, most participants were missing 2 accuracy labels per recording.
We determined the accuracy of these missing responses by inspecting the original event files given by NetStation. We then updated the eventlists produced by EEGlab by manually inserting correct and incorrect labels in place of the (empty) TRSP events. These modified event lists were then re-imported into EEGlab, and we were able to bin trials by accuracy and condition without any hassle.
