wrong timestep deleted with "-delete,timestep=" operator
Added by Guillaume S over 5 years ago
Hello,
I try to remove a selected timestep from a netcdf file using "-delete,timestep=".
Here is a sample of "cdo info" command on the netcdf file before removing the timestep (timestep 605):
...
603 : 2016-05-30 00:00:00 1 131072 0 : -17.054 -0.087363 21.367 : -3
604 : 2016-05-30 06:00:00 1 131072 0 : -21.466 0.18983 22.705 : -3
605 : 2016-05-30 12:00:00 1 131072 0 : -33.474 0.24367 188.04 : -3
606 : 2016-05-30 18:00:00 1 131072 0 : -20.238 0.30653 21.709 : -3
607 : 2016-05-31 00:00:00 1 131072 0 : -17.793 0.25734 22.546 : -3
...
And this is a sample of the same command piped with "-delete,timestep=605":
...
603 : 2016-05-30 00:00:00 1 131072 0 : -17.054 -0.087363 21.367 : -3
604 : 2016-05-30 06:00:00 1 131072 0 : -21.466 0.18983 22.705 : -3
605 : 2016-05-30 12:00:00 1 131072 0 : -33.474 0.24367 188.04 : -3
606 : 2016-05-30 18:00:00 1 131072 0 : -20.238 0.30653 21.709 : -3
607 : 2016-05-31 06:00:00 1 131072 0 : -16.699 0.44606 22.912 : -3
...
As you can see, the timestep 605 corresponding to the date "2016-05-30 12:00:00" in the first case is still present in the second case where it should be not.
And the date "2016-05-31 00:00:00" which corresponds to timestep 607 in the first case has been deleted in the second case (but this not the selected timestep !).
Am I doing something wrong or misunderstanding something ? Or is it an issue with "delete,timestep" ?
Thanks for your help.
Cheers,
Guillaume

PS: everything works as expected with the "-delete,date=2016-05-30T12:00:00" command

hi Guillaume!
could you do a cross-check with the deltimestep,605 operation or possible upload the file?

I don't have this operator with the 1.9.7.1 CDO version, any other alternative to try ? Thanks !

Ah, by fault - this was an old operator, it's not available anymore. I did some checks with testing data and they all worked fine:

So I guess your problem can only be solved having the data.
