Setting all values except one to NaN
Added by Brendan DeTracey over 2 years ago
Hi everyone!
I am having difficulties with what should be a simple problem.
I want to convert my netcdf to a binary mask. I want to replace all values of mmask with NaN, except for 4. I then want to change all the 4 to 1. I am having difficulty thinking of the expr that will do this. :-(
