Bug#589352: ants: Sequence of transformations in WarpTimeSeriesImageMultiTransform produces wrong? result

2010-07-17 Thread songgang
After a quick test, I found a small problem of the second WarpMultiTransform in reproduce3.sh. Here is the output: Step 1 mni-anat: /home/songgang/local/ANTS/gccrel_itk320/WarpImageMultiTransform 3 mni.nii.gz mni2anat-multi.nii.gz -R brain_avg.nii.gz anat2mni_InverseWarp.nii.gz -i

If two images have different image headers, they are supposed to align in the physical space, not in the image voxel space, for warping in ANTS. I noticed you used two different images as references. Could you try both use -R epi_template.nii.gz and verify if this issue still exists?

This is very possible with using the mask. It can be better to include some background. Could you email me this pair of images and masks? I am very interested to think about any way to improve upon this. Thanks -Gang Quoting Michael Hanke michael.ha...@gmail.com: On Thu, Jul 15,
