<div dir="ltr">Thanks for the answer. I am going to volumelookup the predefined sourcemodel which is provided by HCP, MEG_anatomy_sourcemodel_3d6mm.mat, to the ROI_MNI_V4, as the atlas has the MNI coordination systema and the sourcemodel has the bti coordinations system and there is no transform function in the sourcmodel to convert bti to mni, what is your suggestion to do so?<div>Thanks</div></div><br><div class="gmail_quote"><div dir="ltr">On Sun, Nov 6, 2016 at 1:02 PM Schoffelen, J.M.

ft_convert_coorsys is not accurate. Don’t use it if you want an accurate conversion.

Hi Mehdy,<br class="gmail_msg">
<br class="gmail_msg">
You should use bti2spm for this. You can find more specific information on this on the HCP wiki website.<br class="gmail_msg">
<br class="gmail_msg">
Hope that helps.<br class="gmail_msg">

> The provided head model (MEG_anatomy_sourcemodel_3d6mm.mat) in the HCP (Human connectome project) has a 'BTI' coordination system. As I am going to parcellate the data by an atlas which has a coordination system of "MNI", and could not find any transformation
between BTI and MNI, I am wondering if anybody knows what are my steps to do so?<br class="gmail_msg">
