If you want ENMTools to sample background like the Maxent GUI does, you should actually just call it without any background points at all. Give that a shot (set your Nth$background.points <- NULL) and see if you get more reasonable results.

It seemed to resolve when I changed the heading in my .csv from "lat" to "latitude", but I may have tweaked something else, so I guess disregard.<br /><br />Another question tho: I'm getting wildly different predictions when running Maxent via ENMTools and the GUI, am I correct in thinking that dismo (and thus ENMTools) does not invoke the same defaults as the GUI and that to obtain the same prediction I will need to pass along args?Borthttps://www.blogger.com/profile/00645468924230544395noreply@blogger.comtag:blogger.com,1999:blog-4890093519663715581.post-56206120093476027352016-10-26T15:27:21.504-07:002016-10-26T15:27:21.504-07:00I'm not sure what you mean by that.
