These were obtained using ft_dipolefitting to localise EEG recorded event related potentials. Headmodel (BEM) and sensor (128 electrodes) units are in mm and the EEG data (data.avg) is in microV, these are used to make the leadfield whose inverse is used to make weights. The leadfield is not normalised (since the orientation vector is). The amplitudes of the timeseries I'm getting for each dipole are in the range of about +/-500 to 5000. Is the timeseries still in the same units as the input data (i.e. microV, so the timeseries has milliV range amplitude)? If not how can I calculate the units of the leadfield, weights and timeseries?</div><div class="gmail_default" style="font-family:verdana,sans-serif;color:rgb(11,83,148)"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;color:rgb(11,83,148)">Thanks for any help or suggestions,</div><div class="gmail_default" style="font-family:verdana,sans-serif;color:rgb(11,83,148)"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;color:rgb(11,83,148)">Roisin</div><div><br></div><div class="m_-5059116044019522899gmail_signature"><div dir="ltr"><div><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><br></div></div></div></div></div></div></div></div></div>
