Help with an error

[Eduardo Roa]

Hello, nice to meet you, my name is Eduardo Roa and I am doing a connectivity exercise with linkmapper. But I have an error that I have not been able to solve.

My raster layer does not contain negative values, but in the error description it says that I must have negative values.

Attached in .txt of the process, I would be very grateful if you could help me how to resolve the error.

---------------------------------

***Problem encountered executing statement:

"outCostDist = CostDistance(SRCRASTER, bResistance, cfg.TMAXCWDIST, back_rast);outCostDist.save(outDistanceRaster)"

The following ArcGIS error is being reported on line line 577 of "C:\Users\eduro\OneDrive\Documentos\Bibliografia\Conectividad\toolbox\scripts\s3_calcCwds.py":

ERROR 010116: Unable to handle negative values in C:\Link122\scratch\resrast.

ERROR 010067: Error in executing grid expression.

Failed to execute (CostDistance).

Hello Eduardo,

First off, you are using v 2.0, please use v 3.1.0, here: https://linkagemapper.org/Downloads/ 

Also, best to keep the whole folder together, once it is unzipped.

Finally, a majority of analyses use between 10-100 cores on a landscape of analysis, fyi.

Good luck!

Regards,

John
