Hello,<br><br>When I&#39;m trying to run SIENAX with 512x512 matrix image, I get a following error.  Does anyone have an idea what is wrong?<br>I&#39;m running the FSL on Windows PC (total 4GB RAM; 3 GHz processor).<br>By the way it is working fine if I&#39;m running it with 256x256 images, but the error doesn&#39;t seem like memory problem.<br>
<br>Thank you so much.<br><br><br>Command:<br>=======<br>[fsl@localhost temp2]$ sienax
