Hi,<div><br></div><div>    I am running selxavg3-sess under freesurfer 4.5 and I faced &quot;out of memory error&quot; as it started &quot;computing whitening matrices&quot;. Since they are monkey datasets, runs were relatively long (12 runs each 16 min; TR=1.4). I want to know what options do I have here? Please note that, when I applied this command to 3 runs rather than all 12 runs (by making a runlist), I didn&#39;t face this error.</div>
<div><br></div><div>P.S.: I can not use version 5.1 because we don&#39;t have structural scan for this monkey and we just want to check the functional scans without any registration.  I assume it is not possible in version 5.<br clear="all">
