Easily getting number of rows and columns (nx and ny)
Added by Brendan DeTracey over 1 year ago
Hi Everyone. I hope you are all well.
I am using selindexbox to remove the first and last columns and rows from a dataset (or an arbitrary window frame). Using bash I can parse the output of a cdo info command to get the total number of rows and columns (and do any math if I want more than one row/column removed), but is there an easier way to do this? I find myself wishing the selindexbox command (and any index based selection commands) could do this using negative indices, similar to python.
Thanks!
Hi Brendan,
That's a good idea! Negative indexing will be available for selindexbox and maskindexbox in the next CDO version. A new release will be available in the next days. Other operators still need to be identified and will follow later.
Cheers,
Uwe
That would be great Uwe. Will you start counting backwards from 0 or -1? 
Joking...
