Hi there all,
You are right Robin. This is not retrievable. In the first version of BIOMOD, we did extract the training and testing data and associated predictions. However, given the number of outputs BIOMOD can now create (especially if you make projections) we then decided to remove this information for memory and space limitations.
We now only use the testing data for the estimating Kappa/TSS/AUC and then remove the data.
