Hi Anne, 

Shouldn't be a big issue, use the write.table() function on the outputs of the projection function.
This function however takes 2 dimensional information. Our projection outputs are in 4-D.
So you need to inform which layer you want to write the text file for and the trick is done.

For example :
write.table(Proj_Future1_Sp277[ , ,3,1], file="myFile.txt")

Sujet : [Biomod-commits] Projection.raster, GIS and conversion of predictions into formats  readable in ArcGIS

Dear BIOMOD group,
Can anyone please tell me how I convert my predictions from BIOMOD into a format which can be read in ArcGIS? I have used the function Projection.raster to project my models directly onto a stack of the environmental layers I used for the models, however, I continuously run into memory issues, so thought projecting the models onto the full extent of my study area using the Projection function, and then convert these projections to e.g. a text format which can be imported into ArcGIS would potentially be a better solution given the memory issues (which I have tried to solve using all the methods previously suggested even swithing to a PC with 6GB RAM). Any ideas on how to convert these projections??
Best regards,
