OpenJPEG and no such child: Granule errors

Optical Toolbox sen2cor
1

Hello. I am new to using SNAP and sen2cor. My advisor suggested that I use Sentinel-2 data for my thesis work and part of it requires the use of this tool. I have a clean install on a Windows 10 desktop and consistently receive the follow errors no matter which .SAFE I select. I also have selected not to downsample 20 to 60:

image

yet in the output it says:

20 m resolution will be downsampled to 60 m

which doesn’t make sense to me, but more importantly, things seem to otherwise progress well enough until near the end and I start getting these errors:

Progress[%]: 27.64 : PID-24700, L2A_Tables: start export for 20 m resolution, elapsed time[s]: 0.005, total: 0:11:58.683000

Progress[%]: 100.00 : Application terminated with at least one error.
Finished tool execution in 724 seconds

I have attempted to uninstall and reinstall both SNAP as a whole as well as the sen2cor plugins. I have tried both 2.8.0 (what my advisor uses and suggested) and 2.9.0 (latest available to me to download). 2.9.0 fails instantly with

“wrong identifier for xml structure.
unspecific error in metadata
Syntax error in metadata, see report file for details.”

Though, it is a .SAFE and using the .xml within it as instructed.

2.8.0 gives me the best output so far, I DO actually get an output directory, though it is incomplete due to the errors mentioned above.

I would appreciate any insight on how to get beyond these issues. I have a month until the end of the semester when all my data needs to be corrected.
Thank you.

2

I’m still at a complete loss. The errors continue without fail, no matter what I try. Any thoughts or suggestions would be greatly appreciated.

3

What did you select as the output format? BEAM-DiMap is currently the safest.

@Amalia-Castro-Gomez could you investigate?

4

Again, I’m new with this, so I apologize for my lack of knowledge but I don’t have any options for output in the sen2cor screen that pops up. Where do I set that?

Dear cpyywhite,

I imagine you are already doing it, but a general advice is to unzip the S2 L1C product and to not apply any other processing step to the dataset before using it as input for Sen2Cor. Then, inside the Sen2Cor tool, in I/O Parameters, you could try using as input the MTD_MSIL1C.xml file that is inside your unzipped S2 L1C product.

I am going to take a bit more time to explore this in detail.

In the meantime, could we get your advice @marpet ? What do you think is happening?

6

Yes, the MTD_MSIL1C.xml is the file I am selecting:

Should I be selecting it another way?

Hi cpyywhite,

There is already a version 2.10 available. It is available here: Sen2Cor – STEP (esa.int)

Using BEAM-DIMAP as output format is not working.
Sen2Cor is an external tool and does not use the SNAP functionality. SNAP is only providing a way to invoke the tool via a graphical user interface. Sen2Cor writes its own format. It is like the SAFE format.

This issue has been reported already multiple times:
Search results for ‘AttributeError: no such child: Granule’ - STEP Forum (esa.int)

For the latest version 2.10.1 there seems to be an issue in the source code, respectively there is a library missing. At least the following threads are indicating this

It seems that it works in some cases and in others not. Otherwise, there would have been more reports.

I think the sen2cor teams need to have a look at it.

In the meantime, cppywhite, you can try to call sen2cor directly from the command line. This removes the tool wrapper and thereby one source of possible errors.

8

Thank you. I did read the manual and saw the command line section but found it a little hard to follow and understand what the correct syntax was that I needed.

9

Yes, I know. It is not simple to use.

I was able to get the command line version to work but I am getting the same errors. I tried both 2.10 as well as the most recent version, 2.11:

This indicates that there is some issue with sen2cor itself and not with the adapter for SNAP.

Maybe @bdpg can have a look at this?

Dear user,

The issue was investigated internally and there is no error in processing the L1C product within our environment (Windows) with the latest version of Sen2Cor (2.11) fully configured.

As mentioned in point 6) of Sen2Cor FAQ, this problem may occur in Sen2Cor during processing on Windows machines when using long path pointing to the L2A destination folder.
An error in finding/writing a folder/file in the Sen2Cor Post-Processing may be the culprit of this behaviour
We recommend to keep the path_lenght for the input and output directories below 90 characters.

Cheers

@Sen2cor_dev_team

There are a few things you can try to resolve the errors you are encountering while using sen2cor in SNAP:

OpenJPEGLibraryError: OpenJPEG function failure

This error can occur for a variety of reasons, but it is often caused by a problem with the OpenJPEG library. To try to resolve this error, you can try the following:

  1. Make sure that you have the latest version of the OpenJPEG library installed.
  2. Try restarting your computer.
  3. Try running sen2cor as an administrator.
  4. Try running sen2cor from a different directory.
  5. If you are still getting the error, you can try using a different version of sen2cor.

no such child: Granule

This error can occur if the sen2cor plugin cannot find the Granule element in the SAFE metadata. To try to resolve this error, you can try the following:

  1. Make sure that you are using a valid SAFE file.
  2. Try running sen2cor with the --no-validate-metadata option.
  3. Try using a different version of sen2cor.

wrong identifier for xml structure. unspecific error in metadata Syntax error in metadata

This error can occur if the SAFE metadata is not valid. To try to resolve this error, you can try the following:

  1. Make sure that you are using a valid SAFE file.
  2. Try running sen2cor with the --no-validate-metadata option.
  3. Try opening the SAFE metadata in a text editor and checking for any errors.
  4. Try using a different version of sen2cor.

If you are still having problems after trying all of the above suggestions, you can post a question on the STEP forum or contact the sen2cor support team.

Additional tips

  • Make sure that you have enough free disk space on the computer where you are running sen2cor.
  • Try closing any other programs that you are not using.
  • If you are still having problems, you can try running sen2cor in debug mode to get more information about the error. To do this, add the --debug option to the sen2cor command line.

I hope this helps!

I appreciate the responses. The issues I had have semi-been resolved. I can’t state exactly what fixed it but after trying the many suggestions here, latest versions of various pieces, 4 different computers, it finally started working on my Microsoft Surface Pro (the 5th computer I tried) using sen2cor 280 and ONLY that version. Any other version just gave me the same errors as above. It definitely had nothing to do with the directory path length however. I used the same path on all the computers and even tried shorter paths (putting the data directly on the desktop for example) and I still received the above errors but it worked without any issues on the last computer (the Surface) with the original path.
I was able to start actually processing data successfully just a week or two ago.
