Hello everyone.

I have a bug in a process that reads a NetCDF file and makes a Crop using a clipper transformer and then compare the result file with the original file using QGIS, compare point to point and some values ​​coincide but others, in the file result file do not coincide, it has a negative value and the difference between that value and the original file for the same point is a constant, for example in the result file the value is -0.588 and in the original file it is 0.436, the difference is 0.436- (-0.588) = 1,024.

The clipper parameters are like this

If someone has had this problem and can help me

Thanks in advance
