Actual behavior:

I’m analyzing MR images, and am normalizing the images using the following method:

  1. Subtract the mean of the non-zero intensities
  2. Divide by the standard deviation of the non-zero intensities

This results in a smaller range of intensities (between 0 and on order of ~10). In order to have a reasonable number of bins, I’ve been using fractional bin width values; e.g., 0.25, for the Radiomics input.

I see that fractional values are accepted, but wanted to verify that using fractional bin widths is valid. Thank you for any advice.

Yes, fractional bin width is valid.
