Error: java.lang.NullPointerException in GPT , no error in SNAP

SherinSony · May 2, 2018, 5:50am

Hi Friends and @marpet ,

I am getting the below error, though the L1C was converted into an L2A in 241 secs.

I have installed sen2cor via SNAP 6 , Using Py 3.4.3 with snappy:

Only in gpt interface (no error in SNAP GUI) :

Hi , Just to add on
There is no difference in the file count and folder size (L2A foldeer) created by gpt command line and SNAP gui with sen2cor:

obarrilero · May 3, 2018, 10:06am

Hi,

I am not able to reproduce your problem. Have you updated your SNAP installation? Are you able to open the output product in SNAP?

On the other hand, in my opinion, to run sen2cor via GPT is an error. First of all, you can execute directly sen2cor by using the L2A_Process command in your sen2cor installation. When you execute it from gpt, it is similar to run the graph Read->Sen2Cor->Write, the problem in this case is that Sen2Cor already writes the output, so in fact, you are writting the output twice (Sen2Cor writes it in SAFE format at the same folder where it is the input L1C product and then the “Write” operator writes it in BEAM-DIMAP format, by default in your user folder and with the name “target”).

Dear

Strange thing is that when i switched to a new VM, all these errors vanished into thin air. Now after 3 months , when i had to replicate this setup on another machine , again the bombing has started ! It is soooo inconsistent !!!

All the work has been delayed on this new machine now.

I checked my user folder , but there is not output generated.

I installed sen2cor via SNAP 6 .
I am using a Windows VM with 8GB RAM.
I need to automate the process using python. So i wanted to keep all python commands with no GUI usage.

Regards
Sherin

obarrilero · July 2, 2018, 7:44am

Have you updated all the plugins? What version of sen2cor are you using?
