Hello hossein27en,

currently OpenViBE does not support GDF files with different per-channel sampling rates.

Our forum user TPAC posted a way to convert some files into readable format here: viewtopic.php?f=10&t=394&p=2051&hilit=gdf+sampling+rates#p2051

Hopefully it will help you to use your files

Cheers
Jozef
