Hello,

We are trying to convert brain vision EEG files using mne_brain_vision2fiff, but the resulting fiff files do not contain any events. This is the command I run:


    $ mne_brain_vision2fiff --header R0026_eref3h.vhdr --out R0026_eref3h.fif

    mne_brain_vision2fiff version 1.7 compiled at Jan  7 2011 02:26:21

    header  file           : R0026_eref3h.vhdr
    output file            : R0026_eref3h.fif

    Read header file : R0026_eref3h.vhdr
    Read header file : R0026_eref3h.vmrk

    nchan           = 4
    sfreq           = 500.0  Hz
    raw data file   = R0026_eref3h.eeg
    raw binary      = true
    raw binary type = 16
    raw endian      = little
    raw nsamp       = -1
    nevent          = 0
    eXimia          = false

    Data will be split into <= 1907.3 MByte pieces

    Writing header to R0026_eref3h_raw.fif ... [done]
    Writing raw data to R0026_eref3h_raw.fif ... Number of samples deduced from the raw file size : 628790
    [done]
    Wrote 1...628790 of 628790 samples total to R0026_eref3h_raw.fif
    Adding directory to R0026_eref3h_raw.fif...[done]


Eeglab finds the events so I assume the brain vision files are ok. Is this a known problem, or does anyone have an idea how to fix this? The files are small so if it helps I could upload them.

Thanks

-Christian
