Hi Sam,

 

Thanks for your interest in MGET. The short answer here is that, most of the time, this problem indicates an installation problem with Python.

 

The long explanation is that the Canny fronts tool is implemented in MATLAB, but MATLAB and ArcGIS are incompatible in a certain way, due to how the developers of those programs wrote them. To run the Canny tool, MGET has to create a child process to run the MATLAB code, rather than trying to load MATLAB code into the ArcGIS process (ArcMap or ArcCatalog). Your messages indicate MGET successfully created the child process and started the Python script that invokes MATLAB. But the Python script failed to load one of the very first MGET modules. This should be impossible: for MGET to arrive at this point in its workflow, that module definitely exists and is loadable. So how can it happen? Usually it means that the version of Python that was used to execute the child process is different than the one that was used to run the original tool from the parent process. So, usually, there are two versions of Python on the machine, and MGET is installed to one of them but not the other. This can happen if you manually install Python yourself rather than relying than the Python that ArcGIS installs, or during certain circumstances when upgrading ArcGIS from one version to another (although I think they have cleaned all of that up).

 

Anyway, to get to the bottom of this, could you please:

 

1.    Save the attached file to your desktop.

2.    Double-click it. A black window will come up for a little while then go away.

3.    The script will create a text file called GetMoreInformation.txt on your desktop. Send that to me.

 

The file is filled with information about how your computer is configured. I can usually figure this problem from that information.

 

All the best,

 

Jason

 

 

Hi

 

I am trying to use MGET to estimate front position.  I am using Data Products/NASA JPL PO.DAAC/MODIS Global Level 3 Mapped SST/Find Canny fronts (also tried Cayula Cornillon fronts). 

 

I get the error below and I can not find any solutions online. It appears to be a Python linked error. Does anyone know the cause of this?

 

Many Thanks

 

Sam
