[Eeglablist] A problem on loading ahdr/amrk/eeg files with EEGLAB

Ho Kihyo,

The bva-io plugin indeed cannot import encrypted BrainVision files.

With which software did you try to export? Removing a header field certainly will not be sufficient to decrypt.

I suggest contacting BrainProducts support how to decrypt and export files for EEGLAB.

Best,
Andreas

But we've found out that we can't load the data with EEGLAB, even we've changed the files as .vhdr files. The data do show trigger codes and other related things, but they don't show anything about brain waves. (Please see the attached file so that you can find out what the problem is explicitly) I do know that the data recorded by V-amp have an encrypted key, by the way. So I've edited the original ahdr file by deleting [Signature] field before I exported it as .vhdr. Is there something that I have missed?
