<br>
... get more disk space :-)<br>

(note: this <(null)> in that message I have fixed now but it is<br>
unrelated to the problem).<br>

<br>
When running the command keep an eye on the disk space: perhaps it<br>
writes the temp files to a very small partition?<br>

nsres3 and ewres3 are not equal, is that intended?<br>

<br>
This is a fairly large amount of voxels: 1.33425e+12<br>
<br>
Likely the need for much temp space stems from that.<br>
