I'm wondering if DIVA has some sort of maximum for the amount of data points it allows during the Bioclim modeling process? I'm working with hummingbird locality data, which can contain a couple thousand unique location points per species. I've previously run some models using plant data (only a few hundred locality points per species) and the contiguous US climate layers at a 30 second resolution...it worked fine, however it took a pretty long time to run (the program never froze up). I tried running some hummingbird data and almost instantly after the .gri file was made the program froze. So, seeing as though it's probably not a climate layer resolution issue, I'm wondering if there's a max amount of data points Bioclim can handle.
Thanks so much!

There is a limit, but I think it is very large. As you can get to the point where you can make a prediction and can create a gri/grd file the number of points does not seem to be the problem. Could you try predicting to a smaller area (e.g. using "draw rectangle") on the predict tab?

Thank you Robert! That
Thank you Robert! That certainly worked and I have been busy running the models. "Draw rectangle" was still a little too large for some of the samples, but "Read from layer" (using the US boundary file) worked for all of them. Thanks again for your help!
