Hi John,
I am still struggling a bit around the issue. It seems that one of the
start datasets, from which I take the data to copy over, has inverted
axes and data insertion indexes. So that seems to be the issue, I
guess the format is not exactly CF. The second dataset, from which I
take only the variable, using the axes of the first dataset, therefore
is somehow mirrored. I was only checking the axes sizes, but will
definitely have to check a bit deeper.
I will have to check further. But at least the code seems to be ok.
Thanks for the reply,
Andrea
