Hello!

I am trying to apply the deobliquing operation coming from a T1 to a PET-FDG glucose map (3d map with values from 0 to 50, in float) using 3dWarp:

3dWarp -card2oblique PET_FDG.nii.gz -NN -prefix PET_FDG_deob.nii.gz T1.nii.gz

Everything is fine, except that the outputted datatype is short (like the T1), and the range of the data is changed. I tried to change the T1 to float before warping, but then the outputted PET data is still in float, but the range is again messed up (from 0 to 4000 maybe).

Is there to deoblique my PET data while preserving the values using 3dWarp (or using another combination of programs)?

Thank you!

Michael
