Apologies, the data was somehow corrupted in downloading and its now working after I re-download it, I can open it. Thank you Jmalik for your response.

Hi SNAP Team,
Sorry I thought I succeeded opening my level 1C data yesterday but actually not. He can open the xml data but when I try to display individual bands or RGBs it just appears as black and I got this problem only after I upgrade my SNAP to SNAP3 yesterday. Please help how to fix this.

Could you please send us the log file and the full path to the product? I see you’re on Windows, what version of Windows?

Mussiella · April 15, 2016, 3:04pm

Here is it Nicolas:
I am on Windows 10 and the Full path and log file for data is:
D:\Reference Materials\SENTINEL-2\Data_test\Data\18082015\S2A_OPER_PRD_MSIL1C_PDMC_20150818T101216_R065_V20150806T102902_20150806T102902.SAFE

Hi,
Can some one help with the above issue please. I have uploaded the log file the full path to the data. Thank you

Mussiella · April 19, 2016, 9:05am

Hi SNAP team,
Could you please advise me on the issue, I have uploaded the necessary information, I can open the level 1C data in SNAP 3 but if I try to display it its appearing only black screen. Thank you.

Good day SNAP Team,

I experience the same issue initially reported by Mussiella, i.e. I cannot open Sentinel-2 L1C data (xml file). SNAP reports this error:

java.lang.NullPointerException

SNAP Version 3
S2 toolbox version 3.0.2
Platform: Mac OS X 10.7

Thanks for your support!

@Mussiella can you please try moving the product at the root of your HDD.
There is a known issue for Sentinel 2 products which have too long paths for Windows to manage (this will be fixed later by the Ground Segment).

jmalik · April 28, 2016, 3:02pm

@carminemaffei this might be a completely unrelated issue

Please open a shell and execute this :

$ ~/.snap/auxdata/openjpeg/openjpeg-2.1.0-macosx/bin/opj_decompress
$ ~/.snap/auxdata/openjpeg/openjpeg-2.1.0-macosx/bin/opj_dump

and post the results here

carminemaffei · April 28, 2016, 3:24pm

@jmalik thank you for your reply. Both commands provide a “Segmentation fault: 11”

Hi Julien,

These seem to work:

I brutally replaced this distribution of openjpeg into my .snap folder, and now I can successfully open L1C product!

Thanks for your help. Please let me know how I can help with further tests

Regards,

Carmine

jmalik · April 28, 2016, 3:50pm

@carminemaffei Many thanks for early testing, I’m preparing a SNAP module update

carminemaffei · April 28, 2016, 3:58pm

I volunteer for testing on this platform!

carminemaffei · May 23, 2016, 10:28am

I confirm that the latest update of the S2 toolbox, as of today, solves my problem

omran.alhammadi · May 23, 2016, 1:40pm

Hi All,

I just update SNAP to the latest version 3.0 but unfortunately I still cannot open L1C data

is there any solution for that

Regards
Omran

Could you send us the full path to your product? There are sometimes problems with path under Windows.

omran.alhammadi · May 23, 2016, 1:49pm

C:\Users\user.name\Desktop\sentinel2_images\S2A_OPER_PRD_MSIL1C_PDMC_20160110T155054_R021_V20160110T085036_20160110T085036.SAFE

Nicolas · May 23, 2016, 2:06pm

Thanks for the path. There is indeed a problem with the path length, if you move your product up you should be able to open images. We’re also working on a module update to improve the way long path are handled (also fixing problems of path with special characters). It should be available within a couple of days.
