[Eeglablist] error message loading in bdf files

[Laura Batterink]

Hi,
When loading bdf data into EEGLAB, I sometimes receive the following error message: "warning sopen event onset (TYP=BA) and event offset (TYP = 80BA) differ."  This happens both when I load the data through the GUI or when I call the pop_biosig function through a script.  Even though I get this error message, EEGLAB still reads the data in, seemingly without any problems.  I was wondering if anyone could tell me what this error message means and if it's something to be concerned about.

Thanks very much,

Laura
