Hi Pedro,

Saga is at version 2.3.1.

Here attached some pixels of the datasets.
According to the formula I put in the previous email, you have:
a=Z_top_res.tif
b=t_top_res.tif
c=temp_rical.tif

Thank you for your help, and for any info you can give me to help me!

Eugenio

Hi Eugenio,

What SAGA version are you using?

Can you share some sample data?

Best regards,
Pedro

Hi all,

I'm in trouble with Saga Raster Calculator in QGIS 2.18.9 3a16a4e installed
via deb package on ubuntu 17.04.
I set this operation on three raster layers:

ifelse(a<500,0,((b-c)/a)*1000)

I got the resulting map, but checking the computation the pixels have no
correct values.

I tested the same operation in a proprietary software, and with
astonishment, I see that the computation
works fine. I cannot believe that! So I think I'm wrong somewhere in the
raster calculator module.

Can you help me?

Eugenio
