I am Nere Zorrozua, a student in the Universiy of the Basque Country (EHU-UPV) and I write to you to ask for help. I am doing the final master work about habitat suitability modelling and I will be very grateful if you could help me. I am using Marine Geospatial Ecology Tools to make models, using 4 environmental variables' rasters to predict one biological point featured variable. It seems I do not have problems to fit a GAM model using a formula and it seems the results of predicting GAM from table are correct too. But when I predict the model from rasters, the output raster has wrong values, being values of some million some of them. I am not able to find a solution to this and I will be extremely thankful if you help me with this.

Sorry becouse of my poor english and thank you very much for you help.

Best regards,

Nere Zorrozua
