@abruescas Oh thank you so much…this can be helpful .
I tried the new_test_snap file u gave it opened at first.
Then I modified the file (deleted one row) to see if it still works and while saving it got this error.
further which it did not open in SNAP again.
So I decided to use the python code.
I have a query though. Please excuse me for being novice.
in the python script based on my limited understamding we have to manually enter the values as
now if this csv file is smaller in size this cud work but i have 28000 rows and more than 5 columns.
could you guide me on how i can proceed with such big dataset ?
