RE: Space directions smaller than 1
Hi,
Here is what i get with pixel size=1
File format: Nrrd image file [File].
713 x 788 x 20 voxels
Original image orientation: LPS
Uniform volume
1.000000 x 1.000000 x 8.000000 [] voxel size
712.000000 x 787.000000 x 152.000000 [] volume size
Volume origin (0.000000,0.000000,0.000000)
Image-to-physical matrix:
1.000000 0.000000 -0.000000 -712.000000
-0.000000 1.000000 -0.000000 -787.000000
0.000000 0.000000 1.000000 0.000000
0.000000 0.000000 0.000000 1.000000
And here with pixel size = 0.1
File format: Nrrd image file [File].
713 x 788 x 20 voxels
Original image orientation: LPS
Uniform volume
0.100000 x 0.100000 x 8.000000 [] voxel size
71.200000 x 78.700000 x 152.000000 [] volume size
Volume origin (0.000000,0.000000,0.000000)
Image-to-physical matrix:
1.000000 0.000000 -0.000000 -71.200000
-0.000000 1.000000 -0.000000 -78.700000
0.000000 0.000000 1.000000 0.000000
0.000000 0.000000 0.000000 1.000000
A part from the obvious scaling, the output looks exactly the same. I am reassured since I guess this means that the transformations are computed in the same reference frame.
I am currently using version 3.2.2 for Linux, I will try to update and tell you whether the problem still appears.
Thank you,
Best,
Tommaso
