<p>Dear Qin,</p>
<p>The issue seems to come from the <i>"extent of rotation</i>"
variable. A numerical value is expected here and apparently it is
not the case in the brain_phantom.h33 file you use. However this
value is not used currently by castor, so you can either delete
this line of provide any value to bypass this error.</p>
<p>Best regards,<br>
Thibaut<br>
