<p>Dear simNIBS,</p>
<p><br>
</p>
<p>Thank you for creating such a great tool! I am new to simNIBS and <span style="font-size:12pt">have a few basic questions:</span></p>

<p>1) I have run segmentation using headreco, which I read should preserve the original coordinates of the structural file. Is it sensible to use target co-ordinates derived using SPM as coordinates for a TMS target in simNIBS? I am hoping that a real world
xyz coordinate in SPM is the same as an xyz coordinate in simNIBS.</p>
<p><br>
</p>
<p>2) The .txt files created by simNIBS' normalisation to MNI space (e.g. MNI2conform_6DOF) look very different to the normalisation parameters created by SPM12 (e.g. s*seg_sn.mat). Is this expected? In particular, values in the fourth column from SPM range
up to ~200, but only up to ~10 from simNIBS. Is there a relationship between these files or should I not attempt to equate them?</p>
