image resampling using IPT

Hi,
I have some medical images with pixel dimensions of say 1x1x5.5 mm
(x,y,z). I would like to tranform the images using a prespecified
transform and then resample them using the image processing toolbox
(IPT), ie. using maketform, tformarray etc.
It seems to me that these IPT commands operate on arrays, using the
array index as a coordinate and this is giving me some problems.
Specifically, is there a way to make the interpolation (in
makeresampler) non symmetric - in the sense that I would like the z
dimension weighted differently to the x,y dimension when resampling is
done.
Do I have to create a custom resample function for this or is there a
way to do it?
(To the IPT developers: ) Wouldn't it be good with an option to input
coordinates into tform array or is this functionality already covered
or easily obtainable otherwise?
Cheers
Soren
