[Eeglablist] Importing preprocessed, epoched data from BVA

[Arnaud Delorme]

Dear Pete,

yes, I do not think EEGLAB interprets properly segmented EDF+ files returned by BIOSIG.
Would you mind to send us your data file (ideally upload it in a bug report at http://sccn.ucsd.edu/eeglab/bugzilla) and we will make sure it works as expected.

Thanks,

Arno

That may have been the issue.  I still don't know why the EDF+ isn't reading properly, but this works for now.  Thanks again!

All of my plugins for importing different data types are up-to-date.   I've tried exporting in EDF+ format, but EEGlab will only read the files as raw, continuous data -- not the preprocessed, segmented data from BVA.  I've also tried doing the general data export into .dat, .vmrk and .vhdr files, but when I try to import the .dat file, I get an error message saying the data exceeds index dimensions or it just does not read the file at all.
