Volume tools does not specify the units for the dilation radius or soft padding width. I think it is pixels, but would it be possible to specify this in the UI (e.g. “Dilation Radius (pixels)” instead of just “Dilation Radius”)? It would make it clearer for users I think (especially given that in other job types such values are expressed in Å).
I also wonder if it would be better to express this parameter in Å - currently, if the user performs a resampling operation and a dilation/soft padding operation at the same time, the dilation and soft padding widths are expressed as the number of resampled pixels (meaning the edges/dilation extent are twice as wide if the user inputs the same values while resampling to half the box size)
