Error Centrality mapper

[Juan Gerardo Bravo]

Hi John and community,

First of all, thank you very much for this amazing tool. I have been working with it for a long time, and it has been extremely useful.

I would like to ask for some help regarding an issue I am currently experiencing with the additional tool Centrality Mapper.

I am modeling four species. The first one is Leopardus pardalis in Area A, and the tool worked perfectly. However, when I tried to use it for Tapirus terrestris in the same area (Area A), the program started having problems.

At first, I thought the issue was related to Circuitscape, so I uninstalled it and installed it again. However, the same problem appeared. To verify this, I ran another project using Bubulcus ibis in Area B, and everything worked correctly. But when I tried to run Tapirus terrestris in Area A again, it still did not work.

Has anyone experienced a similar issue or have any suggestions about what might be causing this problem?

Thank you in advance for your help.

NOTE: ArcGIS errors are more likely when writing to remote drives or deep file structures. We recommend shallow project directories on local drives, like C:\puma. Errors may also result from conflicts with anti-virus software (known problems with AVG). We have also seen conflicts when writing to synchronized folders like DROPBOX.

Note also that Linkage Mapper tools often work best when run from ArcCatalog instead of ArcMap.
