CDO

I am trying to use cdo to convert some gribfiles to netcdf, but it keeps giving the same error and can't get around it...not even with the help of a post with similar question (https://code.zmaw.de/boards/1/topics/713#message-720)

I have installed cdo today (cdo-current) and get these errors when trying to just show the info of my file:

Error (cgribexGetGrid) : numberOfPoints (39028) and gridSize (62880) differ!

It seems there is some problem with the format or something...the gridSize is correct, but the numberofpoints apparently not, and considers something wrong. I could attach a file, but they are quite big...so I hope you can help me with just this information...

Cheers
