I'm building a species distribution model/habitat suitability model using the package biomod2.

Maxent allows the user to choose one of four output formats (see title) when the Java application is used directly. However, when Maxent is called by functions in the package biomod2 (e.g. BIOMOD_Modeling) there doesn't seem to be an option to specify the output format. Nor is there any indication which one has been chosen. I think cloglog is the default so it is likely that one but I would like to be sure.

This tutorial has some images showing the differences between some of the outputs: https://biodiversityinformatics.amnh.org/open_source/maxent/Maxent_tutorial2017.pdf

Thanks for your help!

  • Did you run a practice model to see what the output is? The way I read this question, it sounds like you didn't try anything first. It helps to know what you have tried and what in particular you got and are dealing with. – shea Dec 23 '18 at 00:43
  • Thanks, @shea. I'm not sure what you mean by a 'practice model'. I've run a Maxent model alongside a Random Forest model and the results (i.e. the rasters) look fairly similar, so I assume both models are working. However, there is no way to tell which of the possible Maxent outputs is being used to produce the raster. I am not sure a) what the default output is when using biomod2, nor b) how to change that setting in case I want to choose one of those outputs – Tristan Feb 04 '19 at 23:38
  • You’re welcome. What I meant by practice was, did you try anything yourself before you asked your question? You didn’t include any code, so it sounded like the question was theoretical. So I was wondering did you make any attempts, even if those attempts were just based on some dummy or practice data. – shea Feb 06 '19 at 04:57

I emailed the developers and Damien Georges told me that the output format for MAXENT in biomod2 is logistic and that (so far) there is no way to change it
