Hi Sebastian,

option 'normchange' will give you the normalized change to baseline (data-meanbsl)/(data+meanbsl)

You can see the formulas for the different options at the end of the ft_freqbaseline code.

I am not sure in which situation you would prefer this option over 'relchange', maybe someone else knows?

Dear list members,

there are several options for baselining in ft_freqbaseline. Most of them relatively intuitively to understand, like "absolute" or "db". However, I wasn't able to find out what "normchange" does. Does anyone of you know (where to find information about this)?

Thanks a lot!
