Re: [Openeeg-list] Data aquisition plus quantitative analysis- float and integer values

Hi Martin,
I've just understood your suggestion to use the file-write element. In fact, I was unaware of this option after unwisely assuming all elements were listed under insert element---all. Indeed, the file-write is under ----target. Sorry for the miscommunication, and thankyou for the resources provided.
After creating an ASCII txt file, integer or float, and connected to a magnitude element, I assume the values written are representative of amplitudes of frequencies within the defined range?

Hi Richard
I am personally tackling very similar problems and would be very happy
to share the information I already obtained. I am also, of course,
very interested in what you already planned in terms of the setup,
hardware etc. What many of us will probably interest most is: will you
document your progress online?

Wow, you get an actual sample of diagnosed subjects for an
undergraduate project? Quite impressive ressources!

I don't know 'that' much about programming, but I can ensure you that
BrainBay, in deed, is modifiable. If you want to expand its signal
processing capabilities maybe you should have a look at this excellect
compendium about signal processing which is freely available online
at: http://dspguide.com/
I would recommend to make a setup in BrainBay which includes a Write
File element. You can make this element write an ASCII file consisting
of your values (whatever they are, just connect to the write file
element you can make all the filtering before writing to file). This
file is easily importable with SPSS (which I use, too).
> 2.1. Software capable of providing bins of frequencies capable of analysis
What exactly do you mean by that?
You can filter frequency spactra which amplitudes you can let BrainBay
write to a file. (Which is in turn readable by SPSS (or any other
statistical analysis software). You can also use EEGlab (if you're not
familiar with it, it's an open source expansion for MatLab) but it's
very advanced and specific I don't know if it is practical to use. Yet
it has some features which other programs don't soupport yet.
My recommendation:
- Use BrainBay to record raw or filtered (--> http://uazu.net/fiview/)
data into an ASCII File and maybe an archive with video to inspect
movements of your subjects later.
- Import data into EEGlab and do artifact reduction (see literature).
Select and export the data you want to analyse.
- Now load this data back into BrainBay and a file which directly
contains the variables you want to measure (eg. amplitude of alpha
band) by adding modules in BrainBay in between the source and the
'file write' element.
- Analyse data with SPSS.
I assume that you have searched the journals for what to look for? If
not, I have picked some examples (see below). If you have access to a
university internet access it should be no problem to access them.
Further, i can only recommend this book:

Success, have fun and keep us updated :-)
