Hello! I am relatively new to OpenViBE and could use some help with using the classifier trainer and processor. I understand that the two boxes are used in conjunction, but I am confused on how to implement them. For my project I want to have the classifier classify based on two features, theta relative power, and alpha to theta ratio, and I have set up the program to where it calculates the two separately. The two are also in separate areas of the brain so I have used channel selectors to filter out the other channels. How do I get the classifier to use the two as features two classify the data? When I try to configure the trainer it has a drop down menu of options to choose from and I am not sure what the options mean. Thank you for your help.
