voxel size change in denoised image #29

Open jguerrerogon opened 3 months ago

jguerrerogon commented 3 months ago

Hello,

Thanks for making this tool available. When I processed the Hardi_150 example following your instructions, the denoised image has a spatial resolution of 1x1x1 mm^3. However, the input image voxel size is 2x2x2 mm^3. The volume dimensions are the same in both input and output 81x106x76.

Any ideas what could be causing this?

Thanks!

Hi, thanks for your interest in our work! We don't particularly adjust the volumetric resolution and did not give special attention to their actual physical resolution. I guess with same volumetric dimensions, it is possible to store the volume with re-sampling or other proper configurations to align the resolutions.
