Hi Mateus,

Can you upload the nifti volume that is not displayed correctly in Caret at "http://pulvinar.wustl.edu/cgi-bin/upload.cgi";. Also, can you capture and upload an image of the volume displayed correctly in SPM5 so that I know how it should appear.

After uploading the files, please email me the names of the files. It may be a few days before I can look into this problem.

I am having some trouble to load nifti images with caret5. The problem is the following:

1) When I try to load an image that has a rotation specified in the header, Caret seems not to apply it properly. The displayed image shows a strange orientation and the voxels size is wrong.

2) However, when the same image is resliced and no rotation is specified in its header, Caret displays the image correctly, the voxels size are correct and the image origin is also correctly located.

Those same images, (1) and (2), are both correctly displayed with SPM5.

The images extension is .nii, so I don't think this should be a problem related to image format interpretation (like interpreting nifti images as analyze and ignoring part of the header information).

Does anyone else has experienced this problem?  Thanks for your help.
