Hi, </div>
<div style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
I am trying to work with a .vhdr file from brainvision. I loaded the data, and did some plots. Then, I tried the ICA, but I ended up with the following error: "No digitization points found". I'm guessing this is related to the set montage. I did a lot of searching,
and I noticed a lot of people have the same issue. Still, I can't seem to find a way to solve this. I am also attaching the file, in case you need. For now, I just want to be able to run the ICA and to properly do the set the montage (if needed). <span style="color:rgb(0,0,0); font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt">I
looked all over the MNE website for solutions, but I simply can't work this out.</span></div>
