Hi everybody,
I started recently to use GPT in order for a user to be able to get a subset of the image only giving me a AOI copy / pasted from Wicket.
I tried to create a very simple graph to write a subset into a .dim
I am using the ‘$’ to be able to use gpt in my cmd console, but when I paste my polygon, I have an error : Error: [NodeId: Subset] Operator ‘SubsetOp’: Could not parse geometry.
Does anybody have an idea ?
Do you have an example of the xml where you’re using the $?
Hi everybody I will answer because I actually found the solution looking pretty much everywhere ! 
When writing “-Ppolygon=POLYGON((…))” I didnt put quotes …
The way to do it is actually : "-Ppolygon=‘POLYGON((…))’ "
Well I hope it helps if anybody has the same problem.
Cheers
Thanks for leaving the solution. Run into the same problem!!
I experienced the same problem as you. Is the script that added $ is in coreg_ifg_computation_subset.xml?
I updated from SNAP9 to SNAP11 and tried to subset using GPT and the following error came up. Can anybody help me or did someone else had the same error?
I used the exact same xml that worked before with SNAP9.

Could you attached the graph?
Thank you
Of course! The graph is attached.
And I run gpt with the following code:
cd C:/Program Files/esa-snap/bin/ && gpt C:/Temp/s1-processingflow_GPT.xml -Pinput_sar=C:/Temp/S1A_IW_GRDH_1SDV_20240107T161018_20240107T161043_052003_0648C5_5D5C.zip -Psubset=‘POLYGON((23.51 48.20, 23.51 48.43, 23.87 48.43, 23.87 48.20, 23.51 48.20, 23.51 48.20, 23.51 48.20))’ -Poutput=C:/Temp/S1A_IW_GRDH_1SDV_20240107T161018_20240107T161043_052003_0648C5_5D5C_processed.tif
s1-processingflow_GPT.xml (6.8 KB)
Do you need anything else to have all the needed information?
In the meantime, I tried it on a different machine with a freshly installed SNAP 11 and the exact same error came up.
For the subset parameter, please replace ‘ with " and see if you still get an error:
cd C:/Program Files/esa-snap/bin/ && gpt C:/Temp/s1-processingflow_GPT.xml -Pinput_sar=C:/Temp/S1A_IW_GRDH_1SDV_20240107T161018_20240107T161043_052003_0648C5_5D5C.zip -Psubset=“POLYGON((23.51 48.20, 23.51 48.43, 23.87 48.43, 23.87 48.20, 23.51 48.20, 23.51 48.20, 23.51 48.20))” -Poutput=C:/Temp/S1A_IW_GRDH_1SDV_20240107T161018_20240107T161043_052003_0648C5_5D5C_processed.tif
That works! Thanks a lot for this rather easy solution.
