In this window you can select the options for the generation of the calculus result.

Name of the layer (1): Introduce the name of the raster layer that will be loaded in the window as calculus result.

Destination of the result (2): Select if you prefer to save the result as a file or to keep in memory. In the first case you will be asked for the path and the name of the file as the calculation will start. If you choose to keep in memory, you can save it later trough the option “Save as” by clicking with the right mouse button over the corresponding layer in the TOC.

Extension of the resulting raster (3). You can choose the extension and the cell size from the following possibilities:

1. Adjust to the input data: The extension of the resulting raster layer will be the union of the single band extensions presents in the calculation. The resulting cell size will be the smaller one amongst the bands presents in the calculation.

2. User defined: Use this option to introduce in the frame Parameters (4) maximum and minimum X and Y values and the output cell size.

3. Use other layer extension: The extension of the resulting layer will assume the ones of the selected raster layer.
