[MINC-development] tfm_input_sampling

[Pellegrini, Stefano (NIH/NINDS) [F]]

Hi everybody,

might anybody tell me why when I use mincresample with 
-transform <identity.xfm> -tfm_input_sampling
I get that in the output file the space:step and space:start attributes (and others, see below) are changed?

for example, this is the input regarding 'xspace'

 double xspace ;
                xspace:varid = "MINC standard variable" ;
                xspace:vartype = "dimension____" ;
                xspace:version = "MINC Version    1.0" ;
                xspace:comments = "X increases from patient left to right" ;
                xspace:spacing = "regular__" ;
                xspace:alignment = "centre" ;
                xspace:step = 0.9375 ;
                xspace:start = -115.585746765137 ;
                xspace:direction_cosines = -1., 0., 0. ;
                xspace:units = "mm" ;

and this is the output:

 int xspace ;
                xspace:varid = "MINC standard variable" ;
                xspace:vartype = "dimension____" ;
                xspace:version = "MINC Version    1.0" ;
                xspace:comments = "X increases from patient left to right" ;
                xspace:spacing = "regular__" ;
                xspace:alignment = "centre" ;
                xspace:step = -0.9375 ;
                xspace:start = 115.585746765137 ;
                xspace:direction_cosines = 1., -0., -0. ;
                xspace:units = "mm" ;
                xspace:spacetype = "native____" ;

thank you very much,
