ERPLAB Toolbox is a free, open-source Matlab package for analyzing ERP data. It is tightly integrated with EEGLAB Toolbox, extending EEGLAB’s capabilities to provide robust, industrial-strength tools for ERP processing, visualization, and analysis. A graphical user interface makes it easy for beginners to learn, and Matlab scripting provides enormous power for intermediate and advanced users.

subtraction and comparison of amplitudes from two test conditions #182

Open mhershkow opened 7 months ago

mhershkow commented 7 months ago

Hi all!

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

733

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.

Dear steve,

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

Sincerely,
