<DIV>Hi Miriam-</DIV>
<DIV> </DIV>
<DIV>We encountered the same problem when importing .bdf's generated by Biosemi. The files are quite large because Biosemi has a uniquely large dynamic range, allowing sampling of ultra-low frequencies. If these frequencies are not of interest to the researcher, then one workaround is to high-pass filter the data above .1 or 1 Hz. This can be accomplished using the free software application LabVIEW (available on Biosemi's website), which will filter the data and convert the .bdf files to much smaller .edf files.</DIV>
<DIV> </DIV>
<DIV>We ultimately ended up using Brain Vision Analyzer to filter the data and export only the primary channels of interest in .edf format. Note that the Matlab export add-in from Brain Vision doesn't always work. <BR></DIV>
<DIV>Good luck!</DIV>

<DIV style="COLOR: #000000">Hi all,
<DIV><BR class=khtml-block-placeholder></DIV>
<DIV>we recently bought a Biosemi EEG System and are now trying to analyse a first oddball experiment recorded with 128 channels. However, EEGLAB continously reports memory failures when we try to read the data in, even though the task manager under windows shows 500 MB of free memory. Has anybody of you encountered the same problem? Do you know how to circumvent it? thanks for any answers and greetings from italy miriam <BR>
