[GRASSLIST:4750] s.surf.idw

[lawrence moran]

Hi,
 
Thanks to Eve for the suggestion- didn't work, though I've figured out its something to do with having an external monitor attached.
 
My next question: getting the following error when running s.surf.idw:
 
Reading sites amp (RedSeaBathyFinal) ...Error:
Decimal field 1 not present in sites file
 
This seems like a fairly simple, yet fundamental error. There were no error messages when I imported this file (an ascii file) and it displays fine. Can anybody suggest where I'm going wrong?
 
Thanks,
 
Lawrence
