<DIV>Dear BIOMOD-Development Team:</DIV>
<DIV> </DIV>
<DIV>I am using ‘BIOMOD’ version 1.1-7.02, on R version 2.15.0.</DIV>
<DIV> </DIV>
<DIV>When performing ensemble forecasting for several species (15-30 occurrence points) I get outcomes that indicate that in some species GLM's are not, or cannot be computed (Evualuation.results.Roc with total score of 0.5; Var.importance with NA). Nevertheless, for most other species it does work, even though I am while modelling with the same environmental predictors.</DIV>
<DIV> </DIV>
<DIV>Hopefully you can give me a hint of where the problem may be.</DIV>
<DIV> </DIV>
<DIV>Pura vida, </DIV>
<DIV> </DIV>
