On the field trip webpage there is a great tutorial that describes step by step how to define trials, read data and preprocess them. You may adapt it to the EGI data format. See <a href="http://fieldtrip.fcdonders.nl/dataformat">http://fieldtrip.fcdonders.nl/dataformat</a> to see what data format FT can read (EGI is among them). See also on this webpage what extensions your file needs.</div><div><br></div><div>Best,</div><div><br></div><div>Stephan</div><div><br><div>

I am using a 256 electrode EGI system and trying to simply read in data collected by someone else. First, how can you determine what format the data was saved in? There are no file extensions. Second, I did get my hands on a .raw file but had problems reading in the data. It ran into a memory error. Is there a problem using a windows machine to run this analysis?
