Problem with Interferometry operation in gpt

Microwave Toolbox Interferometry
#1

Hi,
I am getting the following error while executing that files with gpt.
Could you please provide an insight on why this is happening?

INPUT:

D:\snap\bin>gpt.exe “D:\Deformation-Pre-Processing.xml” -e C:\Users\Cloudsigma\Desktop\subset_0_of_S1A_S1_SLC__1SSV_20141111T142337_20141111T142402_003235_003BC2_5637 C:\Users\Cloudsigma\Desktop\subset_1_of_S1A_S1_SLC__1SSV_20141123T142337_201

for sentinel sar use S-1 TOPS coregistration S-1 back geocodeing

First of all you should update your SNAP installation. With the latest updates the path of the ‘specified file’ should be printed.
In the desktop application just go to Help / Check for Updates

Regarding your command line call:
I don’t understand what you intend by the two paths C:\Users\Cloudsigma\Desktop\subset_0_of_S1A_S1_SLC__1SSV_20141111T142337_20141111T142402_003235_003BC2_5637 C:\Users\Cloudsigma\Desktop\subset_1_of_S1A_S1_SLC__1SSV_20141123T142337_20141123T142402_003410_003FA5_1DDB

Probably you want them as input path. But you have the paths already specified in the xml. The same applies for the target.
When you specify the path in the xml you need to use double back slashes as separator, e.g.
<file>C:\\Users\\Cloudsigma\\Desktop\\subset_1_of_S1A_S1_SLC__1SSV_20141123T142337_20141123T142402_003410_003FA5_1DDB.dim</file>

I’ve updated the graph so that it does what I think what you want it to do.
Deformation-Pre-Processing_updated.xml (4.5 KB)

You can call it from the command line as follows:
D:\snap\bin>gpt.exe "D:\Deformation-Pre-Processing_updated.xml" -e -t "D:\t1.dim" C:\Users\Cloudsigma\Desktop\subset_0_of_S1A_S1_SLC__1SSV_20141111T142337_20141111T142402_003235_003BC2_5637.dim C:\Users\Cloudsigma\Desktop\subset_1_of_S1A_S1_SLC__1SSV_20141123T142337_20141123T142402_003410_003FA5_1DDB.dim

The source product must be the last parameters and I think you forgot to add the file extension dim to them.

Thank you Marpet now it works
