[FieldTrip] units of data sample read from neuroscan avg file is incorrect

[lzyang]

Dear fieldtrip list,
I used ft_read_data to read in .avg files (neuroscan format) to do some
advanced analysis.
data=ft_read_data('sham.avg', 'dataformat', 'ns_avg');
I noticed that the unit of data sample read by this function is incorrect.
Values of samples ranged from -0.1 to 0.1.
I will appreciate if anyone can give me some hints on how to import avg
files correctly using fieldtrip.

Thanks very much!

Best Regards,
