Re: [ITK-users] Reader InvalidRequestedRegionError

Hi Matias,

can you check that all images in that series have size 512x512? A possible
cause is if one of the images has size 484x484.

Orientation and region are not connected too much, I doubt that a funky
orientation would cause problems for region.
