[Eeglablist] EEGLAB file export into EDF and Brain Vision format without channel position

[liao ke]

Dear EEGLAB users,

I have a question about exporting EEGLAB *.set file into *.edf and *.vhdr
format, in which the EEG channel position information is missing in output
files.

When export to *.edf file, the warning is:
Warning SOPEN: HDR.PhysDimCode of the following channel(s) is(are) not
defined:
1 2 3 4 5 6 7 8 9 10 11 ...  (for all 128 EEG channels).

When export to *.vhdr file, the warning is:
Warning: channel location were not exported to BVA (it will use default
         10-20 BESA locations based on channel names)

I am using the  bva-io and Biosig plugins in EEGLAB. Does anyone know how
to export the EEG channel position into either of the two format files? or
know any software that can add channel position information after the files
are created? Any open source software is preferred.


Thank you for your help!

Best,
Ke
