[MINC-users] xfm2param -scale option does not do anything

[Paul GRAVEL]

Dear All,

There is probably a reason for that, but I want to create an xfm file with 
scaling parameters, but it does not seem to work, i.e. the scale 
parameters don't appear and I only get the identity transformation matrix 
as seen below.

Any enlightenment would be appreciated!

Best,

Paul

This is what I did and obtained:

% param2xfm -scales 0.2 0.2 0 test_scale_2D.xfm

% xfm2param test_scale_2D.xfm
after parameter extraction
-center         0.00000    0.00000    0.00000
-translation    0.00000    0.00000    0.00000
-rotation       0.00000    0.00000    0.00000
-scale          1.00000    1.00000    1.00000
-shear          0.00000    0.00000    0.00000

% cat test_scale_2D.xfm
