Error 000732 Topographic Wetness Index #207

Open hoosiernew opened 4 years ago

hoosiernew commented 4 years ago

Hello everyone,

I keep running into the famous Error 000732 while trying to run TWI. It states that "Error 000732: Input Raster Dataset: Dataset E:\GEOG 439\Lab6\elevtwi.tif does not exist or is not supported"

I have made sure that the Input is not located within a Geodatabase and the other suggestions that I found on previous similar posts. I will include the complete error. Any help would be greatly appreciated. Thank you very much!~

Check the following

  1. Does the file "elevtwi.tif" exist in your directory E:\GEOG 439\Lab6. It is possible that it may have been written but not recognized by the Calculate Statistics script. If it is there, try to look at it in ArcGIS to see if there is anything obvious wrong.
  2. Try run from the command line using mpiexec -n 8 TWI -sca "E:\GEOG 439\Lab6\elevsca.tif" -slp "E:\GEOG 439\Lab6\elevslp.tif" -twi "E:\GEOG 439\Lab6\elevtwi.tif" Error messages for this may help with the problem.
  3. As a long shot make sure E drive is not a thumb drive. Writing to a thumb drive sometimes has difficulty. (Though if this was the case previous TauDEM functions may have failed too).
