Hello, thanks for the tutorial. You explained a lot in the setting which is great!!. I wonder if you could upload the talk in the afternoon that you mentioned and follow this part of the class.
Hello, Pablo, I'm Okeyo Fred from, Kenyatta university-Kenya, this is a great piece. I wish I got these when I was doing my undergraduate project. But now I have a reason to improve my thesis project for my master's degree in Environmental Science. If anyone is interested we can work together and co-auth an article on the Predictive model of Cuscuta infestation in 2030, 2060 and 2100 respectively. Thanks so much, Pablo.
Thank you very much for this tutorial, Pablo. Actually, this helped me finalize my undergrad research project, which is due 12 days from today.! Cheers 🫡
Hi, if you have a layer of suitability (e.g. that goes from 0 to 1), then you can reclassify that raster in QGIS using the raster analysis tools (e.g.: reclassify by layer or by table). You can reclassify that layer into those 3 classes by any desired method, or based on your experience.
Pablo, I have a question. I've been following this tutorial series for my own SDM study. I followed the last couple of videos in this series. When I get to the part where I put in my samples and my climatic variables. I get both a Javascript error and also "Sample is out of bounds" error. Not quite sure how to fix that. Ideas?
Hi Nathan, thanks for your message. My guess is that you might have some differences in the coordinate reference system (CRS) between your climate layers and the occurrence data. Could be that: (i) the occurrence data and layers have different CRS, (ii) that the occurrence data file has different order in the coordinates (remember in maxent software you should have a column with the species name, the second colum should be longitude and the third, latitude; and (iii) that some of your occurrences are indeed outside the bounding box of your climate layers. Hope that by checking those you could solve your issue. Cheers
@@pablopcha I double checked the CRS and they look all consistent. Still having the error message. Is there a way I can send my workflow over to have you take a look? Java error according to log is: java.io.EOFException: EOF at cformat.ScanfReader.scanString(ScanfReader.java:710) at cformat.ScanfReader.scanString(ScanfReader.java:635) at density.GridIO.readASC(GridIO.java:212) at density.GridIO.readGrid(GridIO.java:35) at density.Extractor.CachedGridFilename(Extractor.java:60) at density.Extractor.extractSamples(Extractor.java:128) at density.Runner.initializeGrids(Runner.java:152) at density.Runner.start(Runner.java:209) at density.GUI$7.construct(GUI.java:392) at density.SwingWorker$2.run(SwingWorker.java:108) at java.lang.Thread.run(Unknown Source)
Are we able to get the afternoon tutorial, you maybe the only one out there who actually discusses the graphs. There are so many of us out here who can not get past this step.
How can SA_bio11 be important if it has a permutation importance of 0? From what I've read, permutation importance is more important than percent contribution when evalutating the importance of environmental variables.
Hi Thomas, thanks for your message. Both measures of variable importance tell a bit different things. Here you can find an explanation of both: biodiversityinformatics.amnh.org/open_source/maxent/
Many many thanks for this toturial Its make me so impressed that i am going to subscribe your channel at once. Dear sir .. Can u share the ppt of maxEnt with me ?? So that i will share my Gmail with you..

Glad this helped. Thanks for your feedback!
Can you please share your email? Thanks
where is the next part of this video which you say is the interpretation of the maxent result please kindly share the link
nice and clear really
could you please upload the update on this tutorial? it was so helpful. Or if you could provide us with resources that helped you. thank you.
Thanks for the tutorial. If possible how can i get the tutorial for the afternoon class you were talking about. Its so important
Hi John Did you get any response to your question?
@ Pablo is your afternoon class video available ?

Many Thanks Pablo
I've a species modelling map and i want to calculate area of suitability, highly suitable and low suitable in QGIS, how can I do it?
Need help

May I connect with you through your email? I would ask if this sdm fits limited data size or not?

Dear sir ..
Can u share the ppt of maxEnt with me ??
So that i will share my Gmail with you..
Thanks for your feedback. I can forward the slides if you send your email
Sir can you share your email Plz?
