Hi all,
I am trying to mask one image with another using fslmaths.
I am getting the error:
WARNING:: Inconsistent orientations for individual images in pipeline!
Will use voxel-based orientation which is probably incorrect - *PLEASE CHECK*!
I suspect that it is due to the header files being slightly different (attached to the end of this mail).
The two files were created in two different programmes (FSL and Freesurfer) and the header information is very slightly different for each file.
Can I safely ignore this warning?
The results that I am seeing are as expected and it is not crucial that the masking be perfect but I just get very wary when I start seeing error messages.
Regards,
Claude
