Problem step unwrap

[javjrg]

Hello everyone,

I am working with topsApp.py and when in the step unwrap (python $ISCE_HOME/applications/topsApp.py --dostep=unwrap) I have the following error:

imageMath.py -e='a_0*(abs(b)!=0);a_1*(abs(b)!=0)' --a=tmp.unw --b=merged/filt_topophase.flat -s BIL -o=merged/filt_topophase.unw
sh: imageMath.py: command not found

do you have any suggestions about it?

Thank you very much in advance!

It is complaining about not finding imageMath.py

I have the below in my ~/.bashrc to ensure imageMath.py can be found.

export PATH=$ISCE_HOME/applications:$ISCE_HOME/bin:$ISCE_STACK/topsStack:$PATH;

You could try running that export command in the shell and then your usual topsApp.py command.

If this all works you wont need to be running it from inside the ISCE applications folder.

Cheers.
