Looks like this is a bug in the sense that there should be an error-message saying TOPS-coregistration (and other co-registration methods) only work with images from the same track. @mfitrzyk @lveci
I got the same error message even when using two images from the same track.
So I followed the answers in this post Problem with Back Geocoding of TOPs files for a linux system and installed libgfortran3 (via sudo apt-get install libgfortran3).
TOPS Coreg now works as it should and the problem is solved.
I also received this kind of error recently, I just opened Snap as an administrator in windows (I clicked Run as administrator) and the error was fixed even without installing libgfortran3.
Hi everyone,
I have the same problem. We installed the " libgfortran3" but I still get the same error massage.
The images are from the same track, and I use Linux system. The same data, and the same SNAP version on the Window system works without problem!
Has anyone any suggestion how I can overcome this problem in the Linux system?
thanks in advance,
Hello everyone,
I am also having this problem now. I just installed the version 8 of the SNAP. This problem did not occur when I had SNAP 7.0. I also installed libgfortran3 but no improvement. Can someone help?
Thank you!
can you please also install libgfortran5, this has reportedly solved the issue here: Please test the SBAS_snap2stamps
The issue is still there. This is the error:
org.jblas.NativeBlas.dgemm(CCIIID[DII[DIID[DII)V
Thank you
Thanks @ABraun for the suggestion. unfirtunately the installation of the libgfortran5 didn’t help us, and we still get the same problem. Open to suggestions
Hi Anahita,
Did you solved the problem, because I am facing the same error even after installing libgfortran5? If you solved the problem, could you please share the solution?

HI, unfortunately, the problem didn’t resolve!
I did however install Ubuntu on another computer (which I have admin right!) and installed SNAP, everything works properly!
Sorry, I can’t help much here!
Best regards
Hi everyone,
Thank you for your time @Anahita. If someone has any solution please let me know.

Hi everyone,
I am facing a problem while doing back-geocoding of coherence, I use pyrosar and even though I installed libgfortran5 package for performing back-geocoding based on this link. I am getting the following error.

It was working few weeks ago. But now I get this problem. Please let me know the full requirements for the back-geocoding. Whether it needs any special package installation or any special permission? looking for the reply.

I merged both topics, because they deal with the same problem.
Dear ABraun,
I don’t find any particular solution for this error through the link that you provided. whether it depends on S1 toolbox? Because I am getting the xml workflow but the problem is with back-geocoding. If others have solution please share it.

Hi, I solved this by updating the S1 toolbox of the snap. Thank you.

Hi there, I was getting the “Error: [NodeId: Back-Geocoding] org.jblas.Nativeblas.dgemm(CCIID[DII[DIID[DII)V”. I have followed the discussions on the platform, I installed libgfortran5. Then, I got another error. (Error:[Nodeled: Back-Geocoding] split product is expected). I believe it could be a quick thing to solve, but I have struggled. Kindly help with solutions. @ABraun @Anahita @suribabu
Do you use SLC or GRD as an input?
You need an SLC product; and use the “Split” operator (Radar → Sentinel-1 TOPS → TOPSAR Split" , and add it before Backgeocoding.
Moreover, I also don’t see “Apply-Orbit-File” operator in your model builder; did you apply it already?
