Dear FieldTrippers,
<div><br></div><div>I have a question that will probably sound trivial to you, but I haven't been able to find the answer anywhere so I will ask it here. Please bear with me as I am all new to FieldTrip and EEG/MEG analysis.</div>
<div><br></div><div>The data I am working with is in a format that is not recognized natively by FT. I do however possess a MATLAB routine that allows me to read it and store it in a .mat file. </div><div><br></div><div>I have followed the steps described in the FAQ, and reformatted that data within Matlab into a datastructure that is
compatible with FieldTrip, first as one big trial then split it with ft_redefinetrial. </div><div><br></div><div>So far so good, as I can visualize my data trial by trial with no problem.</div><div><br></div><div>Now however, I would like to create my own events relative to a set condition. My data is not marked at all so I have to do it "by hand".</div>
<div><br></div><div>I actually have 6 different experimental conditions and each one of the trials corresponds to the MEG response under one of those conditions. </div><div><br></div><div>How exactly would I go about setting that up in FT ? How do I create events that do not exist in my data? </div>
<div><br></div><div>In other words, how do I give a value to each trial (assuming I know which trial number relates to which condition)?</div><div><br></div><div>It wasn't clear from the tutorials since all the data used always possesses event data beforehand.</div>
<div><br></div><div>Thank you in advance,</div><div>Marco</div><div><br></div><div><br></div>
