Rounding after applyModelNIFTIs

[zyeapp]

Hi there,

is there a reason why there is a line of code that rounds the nifti outputs to integers?

nifti_out = nib.Nifti1Image(np.round(nifti_out).astype(np.int16), affine, header) #fix scaling issue

Because I'm working with images that are pretty low in intensity, and I'm afraid of losing small fluctuations that cannot be attributed to noise. I'm not sure what scaling issue this would fix.

Thanks!

Good question. I'm not sure the original reason behind rounding intensities. I'll have to dig deeper.

Thanks for raising this issue.
