I’m converting a lot of x,y,z points to a grid but am having probs getting xyz2grd to make missing triplets =0.

I used: _ **-di0** _ but missing triplets end up as: _ **NaN** _

Manual states:

> **-di** _nodata_  
> Replace input columns that equal _nodata_ with NaN. Also sets nodes with no input xyz triplet to this value.

Any ideas?  
PS: GMT 5.4.3

Dang. Just found the problem (answer). Nothing like posting something to make you see things a different way!
