subtraction and comparison of amplitudes from two test conditions

[mhershkow]

Hi all!

I'm doing P300 experiment. The subject is presented with different kinds of signals (e.g.: target, novel, standart).

In order to compare graphically between the different condition - I'm seeking a way to subtract the amplitudes of different condition (e.g.: Subtract the values ​​obtained in the Target condition from the values ​​obtained in Novel condition and plotting another graph with only one line presented.

Is there a way of doing it using ERPLAB?

Thank you!

Hi. I recommend doing the ERPLAB Tutorial (available from https://github.com/ucdavis/erplab/wiki). That will show you how to do things such as making difference waves. Steve

Dear steve,

Thank you so much for the help! I've found the answer in the ERPLAB Tutorial!

Sincerely,

Moshe
