Hi John,
I recently downloaded the 3.0 version of linkage mapper and received this error.
Target core areas for core area #1 = [227 229 230 233 239 241 243 245 251]
Found an intermediate core in the least-cost path between cores 1 and 227. The corridor will be removed.

Geoprocessing error on **line 739** of lm_util.py in Linkage Mapper Version 3.0.0:

Failed to execute (RasterToPolyline).

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.
