<DIV></DIV>>Hi Raghu,
<DIV></DIV>>
<DIV></DIV>>What version of ITK are you using ?
<DIV></DIV>>
<DIV></DIV>>There was a bug fixed recently in this application,
<DIV></DIV>>related to the number of parameters used in some
<DIV></DIV>>Transforms.
<DIV></DIV>>
<DIV></DIV>>If you want to use this application, you probably
<DIV></DIV>>want to use the CVS version.
