You would use vop threshold to make a map that has only the values 50-74 and then subtract it from the original map, and repeat with the range 90-110.

Hi,

I have a dataset, its values are 1-255. I would like to modify the density values using a script.
Specifically, I would like to set density values 50-74 & 90-110 to the value of zero.
Is there a way to do that using scripting, or do I need to do that using python?
