I have tried to run this command 2 times and it does not seem to finish the command.&nbsp; The log file just says:<br>Em registration (date/time)<br>CA Normalization (date/time)<br>CA Reg (date/time)<br><br>The log file ends each time with 
<br>Left_Thalamus_Proper (10): linear fit = 1.00 x + 0.0 (4319 voxels, overlap=0.599)<br>aligning Right_Thalamus_Proper...<br>source mean =83.5658, std = 26.5322<br>X:99-132; Y:128-155; Z:103-141<br>gca peak = 0.06253 (102\n\n
<br><br>then that is it.&nbsp; No formal error presents but there is nonprogression.&nbsp; Any ideas?&nbsp; Thanks (again...and again)<br><br><br>
