<p>Thank you!</p>
<p>One more thing: If you opt for transforming simulation to nifti
images, you also need to be carefull only to consider gray
matter voxels in the analysis. For that, you can use the file or
the masks in the m2m_subID/SUBID_final_contr.nii.gz or generate
tissue masks with the "msh2nii" command (try "msh2nii --help") </p>

<p>1- Depends. if it the head model was created with
"headreco", the space is preserved so you can just use
world coordinates from the original scan. However, if the
model was created with "mri2mesh", changing to MNI space
is probably a good idea as this pipeline changes the space
of the images.<o:p></o:p></p>

<p>Alternatively, you can transform simulation results to
NifTi files and do the analysis there. There are several
ways to do this in SimNIBS, such as setting
Edit->Options->Interpolate to a nifti volume in the
GUI, setting map_to_vol=True in scripts or running
"msh2nii" on a ".msh" file.<o:p></o:p></p>

<p>The code looks fine, but it's weird it takes so long.
In every machine I've tried it runs in a few seconds.<o:p></o:p></p>
