As long there are only warnings the result should be okay.
Maybe someone from s2tbx can comment on this and tell what the meaning of the warnings.

Hello,
thank you for info

As @oana_hogoiu already indicated.
In the processDataset.bash file at line 9-11 the PATH is extended to include the path to gpt.

# adapt this path to your needs
export PATH=~/progs/snap/bin:$PATH
gptPath="gpt"

This is missing in your code. You could instead use the absolute path to gpt in your loop.

Sorry I don’t understand, I don’t know the meaning of all instruction, so I have copied them fro RUS training, below the code i try to use, where i must put the other instruction?

#!/bin/bash

output_folfer=C:/Users/Concetta/Desktop/S2/pr
nameStart=S2A_MSIL2A_
nameEnd=.din

for i in (ls -d -l C:/Users/Concetta/Desktop/S2/*.zip) do product_basename=(basename i) ac_date=(echo $product_basename｜cut -d ‘_’ -f 3)
Output_pathname=$output_folder$nameStart$ac_date$nameEnd
gpt C:/Users/Concetta/Desktop/S2/resample-GPT.xml -PInput=$i POutput=$output_pathname
done

my bin path is: C:\Program Files\snap\bin

may you give me some other information

#11

orry i had some problem of copy

#!/bin/bash
output_folfer=C:/Users/Concetta/Desktop/S2/pr
nameStart=S2A_MSIL2A_
nameEnd=.din

for i in $(ls -d -l C:/Users/Concetta/Desktop/S2/*.zip)

do
    product_basename=$(basename $i)
    ac_date=$(echo $product_basename｜cut -d '_' -f 3)
    Output_pathname=$output_folder$nameStart$ac_date$nameEnd
    gpt C:/Users/Concetta/Desktop/S2/resample-GPT.xml -PInput=$i POutput=$output_pathname
done

I’ve seen in one of your screenshots that you had the processDataset.bash open.
That’s why I was referring to it.
The bulk processing with SNAP is explained in the Wiki this is where the script comes from originally:
https://senbox.atlassian.net/wiki/spaces/SNAP/pages/70503475/Bulk+Processing+with+GPT

I see that you are using Linux bash script on Windows. This can’t work.
Take a look at the wiki page. There is a Windows script available too.

thank you very much for reply

#14

sorry, do you think that if I crete a linux partition on my PC it work?

#15

Maybe. You can also try a virtual machine. But still the path to gpt can be an issue.

#16

thank you again
