Problem with prediction map in wallace

[léonard AGBODAN]

Hello everyone,
I'm finding it difficult to get out the prediction map of A. africana' distribution in Togo. The modelled areas are in the form of spot (arround data collection points), but I would like to have them for the whole country (or the area delimited by blue). Please find enclosed the map obtained.
I need your help to perfect it.
Yours sincerely

How are you delimiting your study extent (the Process Envs component)? It's possible you are using a very small point buffer. See the guidance text for information on how to choose a background extent (the Component Guidance tab a few tabs over from the Map tab). To paraphrase some of the guidance included, the extent should include areas where the species is likely to be at environmental equilibrium, and the study region should not include geographic areas that the species does not inhabit due to dispersal barriers. Inclusion of such areas will send a false negative signal, biasing the model’s estimated response to the environment.

If you need to choose a small background extent to build the model, you can continue on to the Transfer component. This component takes the model you've built and transfers a prediction to a new time/space/environments. Choose the Transfer to New Extent module. In Step One, use the polygon drawing tool to draw the rectangle you've shown in the attached screenshot, and then in Step 2 choose a threshold or leave as continuous and click Transfer.

Let us know if you have any other questions.

Good evening,
I was able to produce all maps with wallace and I would like to express my thanks to you for your help throughout the process.
I would like to identify the bioclimatics variables used to build the model. I have downloaded all the plots of the variables as a function of probability of presence (cloglog), and the Maxent Lambdas File.
I would like to have some orientations or documentations to be able to interpret and discuss the model (plots and lambda file)
Best regards and thanks again

Check out the "How does the prediction depend on the variables?" section in the Maxent tutorial, but I recommend skimming the whole document for information on how MaxEnt works (keep in mind, Wallace harnesses MaxEnt either via the maxnet package or maxent.jar). It also includes information on the lamdbas file. 
https://biodiversityinformatics.amnh.org/open_source/maxent/Maxent_tutorial2017.pdf  
The information in this tutorial (and more) is summed up in the component and module guidance texts included in Wallace (the taps over from the map). You can also check out the references cited for additional information.
