Customized Formula option in some Neurofeedback Software

[Guest guest]

Does anyone here use a customized formula feature on their Neurofeedback

software? I'm wondering what that's used for?

For instance, there's an option on my software that allows you to type in

formulas such as the following examples:

1) EEG1+EEG2

2) EEG1

3) EEG1-EEG2/EEG1+EEG2

4) EEG1/EEG2

With my software, there's a list of training options that I can choose from

(amplitude, custom, coherence, ect.). When I highlight " custom " , I can then

type in formulas from which to train from. Is there a complete list somewhere

of all the commonly used formulas available? I'm wondering what each of these

are used for or what they mean?

I've tried searching for info. on this with no luck. You guys (thanks to Pete

in particular) were very helpful in answering my questions in regards to some of

the earlier questions I've had so I'm posting this to see if someone has any

answers to this basic but hard to find info.
