What are the input products? It’s likely something is unexpectedly missing in the input products if they are not SLC SAR products or if they are just a tif file without orbit information etc. In any case the operator should be more robust to tell us what went wrong. With your input we can fix this.

Hello everyone,
i am processing two sliced assembly s1-b dim products and i am getting an operation exception error (org.esa.snap.core.gpf.OperatorException: Interferogram: org.jblas.NativeBlas.dgemm(CCIIID[DII[DIID[DII)V)
during the interferogram formation step, although coregistration looks fine.
Any clue about what i am doing wrong?
Thank you in advance

Hi @elenaath
Were you able to point out the reason for this error? We are processing a number of interferograms but getting this error for one pair.

Hi,

I had the same error on a fresh Ubuntu 16.04 installation when trying to form an interferogram with the most recent version of SNAP (5.0.4).
(org.esa.snap.core.gpf.OperatorException: Interferogram: org.jblas.NativeBlas.dgemm(CCIIID[DII[DIID[DII)V)

It turned out that a library was missing. After installing the packet “libgfortran3” Interferogram formation runs fine.

@developers: Could you include checking for this dependency in the installer script?

Thanks,

Lukas

Thanks, that is the solution!

Same problem, same solution. Lubuntu 17.10 x64

I use Ubunto and I have same error on Back-geocoding of 29 S1. I don’t have any problem in Win 10 but in not in ubuntu. error: org.jblas.nativeblas.degmm…
should I remove Ubuntu and install Lubuntu?

Dear @hamidbanan,

please have a look if this is a possible solution, it might be related to your error I guess.

Dear @thho
thanks for your guide, I will check it.

Thanks! I had a similar error with “Coregistration” and running sudo apt-get install libgfortran3 in my Ubuntu 18 LTS solved the problem.

it is impossible to install libgfortan3 in ubuntu 20.04
I must return to 18.04

I also encountered this problem, my operation systems is ubuntu 20.04, and i can’t install the libgfortran3

Hi @aTnT @thho ,

I have the same error in SAR corregistration :Error: [NodeId: Back-Geocoding] org.jblas.NativeBlas.dgemm(CCIIID[DII[DIID[DII)V

it doesn’t work for me sudo apt-get install libgfortran3 in my ubuntu18.04

what shall I test ??

Thanks.

please specify why this does not work

Read this thread from the linked post until the end. Be sure to read it completely to check the latest issues with that error and up to date SNAP installations:

Hi CDE
Try installing libgfortran5:
sudo apt-get install libgfortran5
give me a shout if it works.
