[Qgis-user] Problems with raster calculator

[Yves Prairie]

Hi all,

Here is my (frustrating) situation. I have several rasters of the same dimension. I add them and obtain a new raster that works fine with appropriate values at each cell. However, when I want to make even the simplest raster operation on this new raster (like add a constant number or anything else), I get a new raster filled with only zeros. This is very frustrating and I cannot find what I am doing wrong. ANy help would be appreciated!

Thanks in advance, Yves
