Hi Katherine, Your input file grid-size/increment is 1.875 degree (see cdo sinfo output) BUT your "sellonlatbox" is less than the increment or grid-size: longitude box is -68.4 to -69.1 is less than 1.875, and latitude as well. so the only possible solution is as suggested by Uwe (see the above post) - remapping to nearest grid point; so if you try:

cdo sellonlatbox,LON1,LON2,LAT1,LAT2 INAME ONAME. to cut an area deﬁned by – LON1 and LON2 are the lower and upper longitude of your window – LAT1 and LAT2 the lower and upper latitiude of your window – INAME is your input ﬁlename – OUTPUT is your output ﬁlename.

To save space, still using CDO, I then have done this: cdo sellonlatbox,-20,20,45,65 converted.nc out2.nc. Cheers!

you can use nco to write these variables to another file, cdo setgrid should do it, too.
