Thanks John,
Tried to run it on a new project folder with a new Linkage Pathways run and it produced the below errors:
Will try again.

ERROR: Circuitscape failed.
Note: Circuitscape can only solve 2-3 million nodes
per gigabyte of available RAM. The resistance
raster for the last corridor had 32859499 nodes.
Resistance raster values that vary by >6 orders of
magnitude can also cause failures, as can a mismatch in
core area and resistance raster extents.

My resistance surface raster contains values from 1 to 100 and is at a 10m resolution. Does this mean that I need to coarsen the resolution?
Cheers,

Hi Gwali,
The key here I think is "Cannot get exclusive schema lock"
This is oftenan ArcGIS issue. Often caused when the file is open in another program, and then the scehma lock gets "stuck" even when the other program is closed. Quickest solution is to close ArcMap and ArcCatalog, then to open just one, and try the operation again. If that does not work, try deleting the file that is causing the problem. In some cases, such a file was created in linkage Pathways, so in that case, best to start with a new project folder and a new Linkage Pathways run.
Good luck!
John

Dear John,
Thank you again for you swift guidance. It is very much appreciated.
I have five resistance surfaces (representing different landcover scenarios), each contains 125,881,396 cells. 42,129,800 of these have resistance values in, the other 83,751,596 are NoData. Running these with 10 core areas.
Below is the full code where Pinchpoint Mapper fails when I select the option in the Pinchpoint Mapper window labelled ‘Calculate raster centrality using Circuitscape’ and the option ‘pairwise’, which I am trying to use to calculate area-corrected centrality for my core areas:

Hi Gwili,
it is unlikely that is what it means. It looks like there is something else going on. Please send the full error message.
Also, please let me know the area of the resistance surface, or the approximate number of cells. 10 m resolution should be fine for the landscape scale, but not the continental scale. Depends on the size of the landscape though.
Thanks,
John

Thanks John:
- I ran it with the pixel size aggregated to 100m with the conditions I used before and it succeeded, reporting no errors. I see the output rasters, and how it put -1s in the linktable_plus.csv. Where do I go to get a centrality measure for the core areas?
- I am indeed running it in ArcCatalog.
- I ran it previously without ticking the raster centrality box at 10m pixel size and no errors were reported
- When I ran it as all to one it also failed.
Would you advise me to attempt to run it on a more powerful computer? Or aggregate to 20m pixels and try that?
With thanks again for your time,
Gwili

Thasnk Gwili,
Hmmmm. You were right, it may be too many cells, as per the warnings.
"---------------------------------
Warning:
Circuitscape can only solve 2-3 million nodes
per gigabyte of available RAM.
Total physical RAM on your machine is ~7.8 GB.
Available memory is ~2.9 GB.
Your resistance raster has 11818929 nodes.
---------------------------------
Processing link ID #5. Resistance map has 11818929 nodes."
Yes, try your original fix and see if that works. Looks to me like you may only need to resample from 10 m to 20 m cells, but you may want to go to 100 m as a first time test to be sure this is not the problem.
Other thoughts:
2) Try running it in Arc Catalog if you are doing it in Arc map. (Were you already using Arc Catalog?)
3) Try it without clicking the optional box for calculating centrality
and if all the above did not work, lets gather more data:
4) Try it All to one. instread of pairwise.
You can do fixes 1-3 all in the next run, but if you want to be sure to isolate the problem, it is ideal to do one fix at a time.
Good luck,
John

Hi Gwili,Thanks for your patience on this and your thoroughness. nad for the full model dialog.
OK, so, to review at a high level, it worked at 10m, but only when the optional "calculate centrality" box was NOT checked. yes. When that was checked, it did not run. yes However, with that box checked it did run at 100m cell size yes. But then it did not at 20 m. yes, but it also ran at 30m size, Furhter, when it failed, if failed on a different pair of cores, not the same pair each time. yes Please let me know if that is not all correct.So it sounds like the centrality calculation is causing the problems. yes and specifically the 'calculate raster centrality using Circuitscape' tool
This is what I would suggest:
1) Run it at 10 m without centrality option checked. If that works, done and yes it works2) Then run the Centrality Mapper stand-alone tool. done and yes, it produces CF_Centrality values for each linkage in the link table. However, I was also looking to create CF_Central values for each of the core areas to calculate area weighted centrality.
3) Please let me know how that all worked. I may need to log an issue in git hub to fix or remove the optional calculate centrality box in Pinchpoint Mapper.Thanks!JohnJohn Gallo, Ph.D.
