Creating pictures of predictions

[mrsjb...@gmail.com]

Hello all,

I am a post-doc at the University of North Texas and I am using Maxent to model bumble bee distributions in Texas. 

I have just finished a very lengthy run of the program (100 replicates)and I realized after the fact that I had accidentally unchecked the box "make pictures of predictions". I was wondering if anyone knows how to create a figure/picture of the average distribution AFTER having completed the run? 

Thank you in advance for any and all help.

If you had run Maxent in R with the dismo package, you can. But since you used Maxent.jar, unfortunately this is not possible -- unless someone has a fancy Java trick up their sleeve. Reproducibility is Maxent.jar's weakpoint -- consider using saved scripts in R to run your analyses in the future, and this will never be an issue.

Hi,

Totally agree with Jamie about the convenience of using scripts to run Maxent. But there might be a way to map predictions in your case without having to re-run the analysis... I'm not sure, but I think Maxent should have produced several ASC rasters as output (mean, median, SD...). You could load them in R or a GIS and make the maps yourself?

Hope this helps,

Paco

Paco,

Yes, you are right. I misread Jessica's post -- sorry about that. If all you need is images of the predictions, load the prediction ascii files into ArcGIS (requires license) or QGIS (free) and save an image file. You can also load them into R with the raster() command from the raster package and plot() them.

Thanks to all for the information. I guess I need to learn R! For now I have loaded the ascii files into Arc and that did the trick.
