Hi,<div><br></div><div>I would be really very grateful for some help regarding setting layout for EEG. Im analysing (or trying to!) some clinical EEG 10-20 data on epilepsy patients and am struggling to get the layout working using the standardised layout files. My channel names concur with those of standard EEG 10 -20 systems (see below) (<a href="http://en.wikipedia.org/wiki/10-20_system_(EEG)">http://en.wikipedia.org/wiki/10-20_system_(EEG)</a>) </div>
<div><br></div><div>Number of questions - </div><div><br></div><div>1. The EEG 10-20 standard layout does not seem to match what I thought of (and have checked online) as the standard 10-20 format. Specifically - it includes channels Fpz and Oz for example which aren't on the standard layoutand excludes T3 T4 T5 T6 (<a href="http://en.wikipedia.org/wiki/10-20_system_(EEG)">http://en.wikipedia.org/wiki/10-20_system_(EEG)</a>) </div>
<div><br></div><div>2. When I check what my layout should be -</div><div><br></div><div><font color="#ff0000">>> [type]=ft_senstype(datast_A.label)</font></div><div><div><font color="#ff0000"><br></font></div><div><font color="#ff0000">type =</font></div>
<div><font color="#ff0000"><br></font></div><div><font color="#ff0000">ext1020</font></div></div><div><br></div><div>Yep there is no layout file for ext1020 in the standard layout templates that seem to come with fieldtrip to use with ft_prepare_layout.</div>
<div><br></div><div>Given that all the channels are I need are in the EEG1010 file, I hoped that I could use that instead but then I end up with a layout has 80 odd channels when I only need 21.</div><div><br></div><div>I'd be so grateful for any help with this! I'm very sorry if its something very simple but I have been looking at it for many many hours without any luck!</div>
