Re: grdmath problems

Paul:


I get this:
osop@osop-displays2:~$ /usr/src/gmt-4.5.11/bin/grdmath -R0/10/0/10 -I1 X =
1.grd
osop@osop-displays2:~$ /usr/src/gmt-4.5.11/bin/grdmath -R0/10/0/10 -I1 X =
2.grd

EXCH POW MUL = 3.grd
*** buffer overflow detected ***: /usr/src/gmt-4.5.11/bin/grdmath terminated

So will you still need the original files if these dummy files produce the
same error? Please let me know!
