Hi Paul, I don't know if you have heard or worked with eeglab, here they use a dipole fitting without considering the time course in the dipole moments, ¿Can I somehow use the functions of fieldtrip in eeglab to perform dipole fitting and consider the time course in eeglab too?<br><br>Another question: when I perform the example below:<br><br>http://fieldtrip.fcdonders.nl/example/compute_forward_simulated_data_and_apply_a_dipole_fit<br><br>And I compute the dipole fit with the first simulated dataset, I get the next structure:<br><br>dip1 = <br><br> label: {1x128 cell}<br> dip: [1x1 struct]<br> Vdata: [128x250 double]<br> Vmodel: [128x250 double]<br> time: [1x250 double]<br> dimord: 'chan_time'<br> cfg: [1x1 struct]<br><br>And, after define the dipole moment as [1 0 0]' , I go to the dip field and in the field mom (i.e. dip1.dip.mom) I get an 3x250 double matrix.<br>So, when I define the dipole position it is [0 0.5 0.3] and in the dipole fit in the field dip1.dip.pos, I get this same position (aproximated) it is [-2.1186e-008 0.5000 0.3000], but in the dipole moment I don't get the same, not even aproximated, instead of [1 0 0]', I get this [3x250 double] matrix. ¿Am I commiting any mistake or is a concept error? and ¿ How we can interpret this when we have more than two dipoles?<br><br>Thank you for your help.<br> <br /><hr />Connect to the next generation of MSN Messenger <a href='http://imagine-msn.com/messenger/launch80/default.aspx?locale=en-us&source=wlmailtagline' target='_new'>Get it now! </a></body>
