computing ionosphere error

[yunusmuhammaddd]

Hello Everyone!!

I am currently proceed ALOS-2 ScanSAR data using alosStack.py. However, I got several error during computing ionosphere. I Got:
imageMath.py -e='sqrt(a_0a_0+a_1a_1)' --a=amp_tmp.float -o amp_3rlks_14alks.float -t float
sh: 1: imageMath.py: not found

And When I tried to run cmd_3.sh, I got:

Anyone can help to deal this these issues?
Thank you in advance, I really appreciate it!

Did you resolve it? I am facing the same issue

'sh: 1: imageMath.py: not found' means you haven't configured the environment variables correctly, so the command cannot be found from command line.
