iCOR sentinel 2 plugin error

I’m trying to run iCOR to process sentinel 2 images but I’m getting the following error:

/usr/bin/python: can’t open file ‘/opt/vito/icor\src\icor.py’: [Errno 2] No such file or directory
Process exited with value 2
Finished tool execution in 0 seconds

I installed snap 5.0 for Linux (Ubuntu 16.04) with python 2.7. and the iCOR plugin following the instruction and the installation procedures ended without errors.

The iCOR landsat 8 plugin seems to work fine.

Any suggestions?

Thank you in advance!


Hello, I seem to be having a similar problem did you ever get a response or a fix for it?


It seems that iCOR gets automatically set up with a mix of Windows and Linux folder separators.

I have had success with editing the “System Variables” value for icor_py.

Go to:
Tools -> Manage External Tools -> Edit the Selected Operator (notepad icon)

Then edit the Value entry to use forward slashes as shown here:
