Can not detect L1C product in the folder

[hanamthang]

I start MAJA with the basic command:
./startmaja -f /home/metal/Downloads/maja/build-pkg/MAJA-4.2.1/folder/folder.txt -t 60HVD -d 20200405

but the following errors appear:
Error 1:
ValueError: Cannot find ^T?60HVD$ in /home/metal/Downloads/maja/build-pkg/MAJA-4.2.1/folder/repL1
if name of L1C file as: S2A_MSIL1C_20200405T221601_N0209_R129_T60HVD_20200405T233012.SAFE

Error 2:
OSError: No L1C products detected for tile 60HVD in /home/metal/Downloads/maja/build-pkg/MAJA-4.2.1/folder/repL1/60HVD
if I rename L1C file as 60HVD.

What would be wrong in this case? Is it just the name of L1C file?

Many thanks,
Thang

Hi, I have had this issue too !

In MAJA 4.2 (and not in MAJA 3.x) the L1C products should be stored, in your case, in :
/home/metal/Downloads/maja/build-pkg/MAJA-4.2.1/folder/repL1/60HVD (or T60HVD)

Hope it solves your problem.

Hi, thank you for your support. Actually, I tested both:

1. Renamed L1C file to 60HVD or T60HVD but still got error:
   OSError: No L1C products detected for tile 60HVD in /home/metal/Downloads/maja/build-pkg/MAJA-4.2.1/folder/repL1/60HVD

2. Copy the scene in the GRANULE folder of S2 L1C image and then renamed to 60HVD or T60HVD but still error:
   OSError: No L1C products detected for tile 60HVD in /home/metal/Downloads/maja/build-pkg/MAJA-4.2.1/folder/repL1/60HVD

Is it the code error or something with the python library? I used the prepacked binary, extracted and installed MAJA using the file ".RUN". Version of MAJA is 4.2.1.

Hi Thang,

You should not rename the L1C folder. Instead, you should follow this file structure:

/work/S2-L1C
├── 31TCJ
│   ├── S2A_MSIL1C_20180401T105031_N0206_R051_T31TCJ_20180401T144530.SAFE
...
├── 31TFJ
│   └── S2B_MSIL1C_20190717T104029_N0208_R008_T31TFJ_20190717T142616.SAFE
├── 31UFR
│   ├── S2A_MSIL1C_20190821T104031_N0208_R008_T31UFR_20190821T111838.SAFE
│   ├── S2A_MSIL1C_20190903T105031_N0208_R051_T31UFR_20190903T125049.SAFE
...
├── 34WDC
│   ├── S2A_MSIL1C_20200403T105621_N0209_R094_T34WDC_20200403T114509.SAFE
...

If you have that structure, you need to set inside the folders.txt the parameter repL1C=/work/S2-L1C. Any other path is also fine as long as you store your L1C products in that structure.

Kind regards,
Peter

Hi Peter,

Many thanks for the solution that worked. The MAJA can detect L1C Sentinel 2 now.

And I think the section Prepare folder and input files should be updated for the path to L1C and L2A. For new comer like me, I did not know how to set the name of the folder.

[Maja_Inputs]
repWork=./work
repGipp=./gipp
repMNT=./dtm
repL1  =/path/to/L1C
repL2  =/path/to/L2A
exeMaja=/path/to/bin/maja
repCAMS=/path/to/CAMS

[DTM_Creation]
repRAW=./dtm/raw 
repGSW=./dtm/gsw 

repL1  =/path/to/L1C
repL2  =/path/to/L2A

should change to

repL1 = ./work/S2-L1C/31TCJ
repL2 =./work/S2-L2A

or something like that which then enable MAJA detect L1C.

Hi, I've a similar issue. This is my command:

./bin/startmaja -f folders.txt -t 33TWF -s 33TWF -d 20200601 -e 20200630

and this is my folders.txt file:

[Maja_Inputs]
repWork=/media/alex/dati_linux/s2/temp
repGipp=/media/alex/DATI/gipp
repL1 =/media/alex/DATI/L1C
repL2 =/media/alex/DATI/L2A
repMNT =/media/alex/DATI/dtm/
exeMaja=/opt/maja/bin/maja
repCAMS=/media/alex/DATI/netdbl

[DTM_Creation]
repRAW =/media/alex/DATI/dtm/raw
repGSW =/media/alex/DATI/dtm/gsw

I've many images in the L1C folder, like
/media/alex/DATI/L1C/202006/33TWF/S2A_MSIL1C_20200601T095041_N0209_R079_T33TWF_20200601T110247.SAFE/

But I receive the error:

2020-11-29 03:46:58,220 [INFO ] =============This is Start_Maja v4.2.0==============

ValueError: Cannot find ^T?33TWF$ in /media/alex/DATI/L1C/202006/33TWF

It seems strange because with the previous version of Maja I didn't get the error.

Kind regards,

Hi there,

If you used: ./bin/startmaja -f folders.txt -t 33TWF -s 33TWFA -d 20200601 -e 20200630

Your folder should be: /media/alex/DATI/L1C/33TWFA /33TWF/S2A_MSIL1C_20200601T095041_N0209_R079_T33TWF_20200601T110247.SAFE/

I added "A" after 33TWF to make a difference between the two names.

Kind regards
Thai
