<div dir="ltr">Hi Steve,<div><br></div><div>Thank you for your answer and the Fieldtrip hint! Indeed, the reason why I was wondering about importing BVA files, is because I have individually digitised electrode coordinates. Ideally, I would like to import these separately, for precision's sake, but of course if there's no straightforward way, I might just use the default locations.</div><div><br></div><div>Seeing as Brain Vision is a very popular suite in EEG research, it might be good if EEGlab team would support their file format?</div><div><br></div><div>Best,</div><div>Nikola</div><div><br></div><div class="gmail_extra">

In my experience these locations are accurate if my Brain Vision workspace used the standard filenames; so if that solves your issue, then you might not need to import the bva file.<br><br></div>If you still need to read the locations from a file, that might be tricky; I remember I had the same problem (but this was several years ago so I don't know if EEGLAB has changed since then in this regard). I believe (if I'm remembering correctly) what I did at the time was read the .vhdr file into Fieldtrip, and then use that to export the channel locations as an .sfp file, which then EEGLAB was able to read. Since that was a while ago, there may well be a more straightforward way now.<br><br></div>Best,<br></div>Steve<br></div><div class="gmail_extra"><br clear="all"><div><div><div dir="ltr"><div><div dir="ltr"><span><div><br><br>---<br></div>Stephen Politzer-Ahles<br>University of Oxford<br>Language and Brain Lab, Faculty of Linguistics, Phonetics & Philology<br><a href="http://users.ox.ac.uk/~cpgl0080/" target="_blank">http://users.ox.ac.uk/~cpgl0080/</a></span></div></div></div></div></div>
