[Eeglablist] Fw: Error using DIPFIT

Sun Apr 26 02:33:22 PDT 2015

Hey,

i investigated the issue further and can now share additional information
with you:

The Data i load into EEGlab are .mat-Files created with the brain vision
analyser (BVA).
The error message only appears if i load the data using the
'pop_bvaoi'-plugin and does not appear if i use the 'pop_biosig'-plugin. In
addition, this error occurs if i load the raw files (.EDF) using the
corresponding plugin.

I hope this helps in understanding what goes wrong with this error message.

Best,
Claudio
