How to get correct values for GSR, etc.

Post by maarcc2050 »

Hi.

Data channels captured off biosemi can be read correctly by dividing the values 256.(?)

How about GSR, ERG, Plet, and temp? If I read the values off the 24 bit bdf file, how do I arrive at the right values for GSR, ERG, resp, and plet, temp?

Many thanks.
Marc

The units and scaling for each channel is found in the file header, see http://www.biosemi.com/faq/file_format.htm
