Hi, I thought I'd mention a problem I just came across that may have a fix I missed. If not then perhaps it can go into a feature request.
I was performing a mask operation and received an error saying that images weren't in the same space. The relevant code is in the ImageToImage filter base class where the orientation matrices are checked. There doesn't seem to be a way of adjusting the tolerance or turning this check off. My problem image was produced by the spm8 coregistration procedure, and the difference in orientation matrix introduced by rounding (I assume) was only just greater than the hard coded tolerance. I've fixed the problem by explicitly copying the geometry in the input nifti files using the fslcpgeom tool, but I suspect there should be some ITK specific option to deal with this inside a filter. Obviously image information can be copied inside ITK code too. Not sure if there is a "right" way to deal with this issue. _______________________________________________ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Kitware offers ITK Training Courses, for more information visit: http://kitware.com/products/protraining.php Please keep messages on-topic and check the ITK FAQ at: http://www.itk.org/Wiki/ITK_FAQ Follow this link to subscribe/unsubscribe: http://www.itk.org/mailman/listinfo/insight-developers
