Transformix not returning transformation field

[w013nad]

In transformix, it's supposed to be possible to output a deformation field rather than an image. (I'm working with hyperspectral so it's much easier to get the deformation field and transform all the layers individually using the deformation field. Anyway, I came up with a fix outlined below. Note that the fix is tailored to my needs. This is for a 2D image, not sure how it would work for 3D
Originally I did get an output but it was an empty 1x1 stucture

fid = fopen(fullfile(outputDir,'deformationField.raw'));
raw_out = fread(fid,Inf,'float');
out_points(:,:,1) = reshape(raw_out(1:2:end),size_im(2),size_im(1));
out_points(;,:,2) = reshape(raw_out(2:2:end),size_im(2),size_im(1));
out_points = permute(out_points,[2,1,3]);

From there, I'm able to just cycle through and call
for ii = 1:num_channels
out(:,:,ii) = imwarp(moving(:,:,ii),out_points);
end

I originally just ran all the layers through but this comes out to a 1.5 minutes saving per data cube processed.

Also, how to I insert code formatting here? Not used to github.

Thanks, I'll look into this.

Short update. When I did this, my error rates jumped way up. It's still deforming correctly but my RMSE of desired output to actual output jumped form 0.03 to 0.04. Not really sure why.
