Hi All, I have an eeglab epoched EEG dataset that I would like to analyze using MNE. I can export my eeglab \*.set file as a \*.EDF file and convert it to fif using mne\_edf2fiff easily enough. I changed channel names, trigger to STI 014. I can also make an event.txt file. However, when I load the fif file into mne\_browse\_raw I get no data and no channels displayed (same if I load it into mne\_analyze). The time information displayed in mne\_browse\_raw is correct, and the event list shows the events just fine. Just no data. I can load the fif file into matlab using fiff\_setup\_read\_raw and fiff\_read\_raw\_segment and the data looks fine in matlab. Same thing happens when it is an un-epoched file. I have two questions: 1. Am I doing it wrong with mne\_browse\_raw? If so, does anyone have any suggestions. I've copied what is sent to the terminal when I load the fif file below. 2. Given that I can read the file in fine, I should be able to write it out using fiff\_write\_int, correct? I tried using mne\_ex\_read\_write\_raw to read/write the file to see if that would make something mne\_browse\_raw would like. It made a data file just fine, but still nada. Thanks in advance, Jim ## First, loading in the \*.fif file --- Opening /home/jim/Desktop/Studies/EEG/jt\_03/jt\_03new\_raw.fif --- No compensation data in /home/jim/Desktop/Studies/EEG/jt\_03/jt\_03new\_raw.fif Compensation in file : uncompensated Setting up compensation data...   No compensation set.

Hi James, Did you try loading a channel layout from the Adjust menu? In the past I had a similar experience as you (imported data successfully but couldn't see it in mne\_browse\_raw), and it turned out I just had to choose a channel layout for viewing. Best, Steve ---

Hi Steve, Thanks for the tip. I just hit Adjust -\>Selection-\>Add... and could add my channels. Worked like a charm. best, Jim
