<p>​Hello All,</p>
<p><br>
</p>
<p> My apologies for posting about an issue which has already received considerable coverage. I am trying to use mne_setup_source_space with the --morph option. I am doing this because I am working on an analysis which requires all subjects to be in a common
vertex space early on (so mne_make_movie is too late).</p>
<p><br>
</p>
<p> For example:</p>
<p><br>
</p>
<p>mne_setup_source_space --subject <subject_id> --morph fsaverage</p>
<p><br>
</p>
<p> I am receiving the "double occupation" error which is mentioned numerous times in this forum:</p>
<p><br>
</p>
<p>Source space vertex moved from 158588 to 112571 because of double occupation.<br>
Source space vertex moved from 39211 to 158591 because of double occupation.<br>
Source space vertex moved from 158587 to 126593 because of double occupation.<br>
Source space vertex moved from 126593 to 126594 because of double occupation.<br>
Source space vertex moved from 126593 to 126592 because of double occupation.<br>
Source space vertex moved from 126594 to 126595 because of double occupation.<br>
Source space vertex moved from 158590 to 87784 because of double occupation.<br>
Source space vertex moved from 87782 to 112573 because of double occupation.<br>
vertex 27923 would be used multiple times.<br>
Source space creation failed<br>
Temporary files removed.</p>

</p>
<p> My understanding from the previous posts is that this error can be avoided by either using --spacing with any distance given, or with --ico and a relatively small number of vertices (according to table 3.1 of the 2.7.3 manual, this means smaller absolute
integer values, such as --ico 3 or --ico -4). Unfortunately I am still getting this error regardless of what I give to --spacing (1-21 have been tried) or with both larger and smaller values for --ico (1-7 both positive and negative).</p>

<p> This problem does not appear to be limited to any particular subject in my analysis, nor to the fsaverage brain. I am working under Ubuntu 13.10, and my version of mne_make_source_space is as follows:</p>
<p><br>
</p>
<p>mne_make_source_space version 2.5 compiled at Jan 6 2011 02:25:18</p>
<p><br>
</p>
<p> Am I understanding the previous posts correctly? Is there any new progress on this issue? Are there other ways to avoid it? (I see there is a setup_source_space in the Python code - should I try that?)</p>

<p> Thanks again,</p>
