Gmtinfo prob

Q&A
1

I am creating a grd file using a script with the following commands:

set grd_file = Site_a.grd
nearneighbor <data.txt -G$grd_file -I0.10 -i0,1,2 -N1/1 -V $region -S0.15
gmtinfo $grd_file

which gives all the expected info.
However, outside of the script if I just type

gmtinfo Site_a.grd

i get

gmtinfo: NetCDF variable y has different dimension (71) from others (81)

Have very little experience with the details of NetCDF files. Can someone explain what the error means?
I also can’t understand why the same command gives different results inside and out side of a script (have checked and the same command is being called each time).

Using GMT 5.4.3 - I know, please don’t tell me to upgrade!!

different gmt versions? (as grd format changed to NetCDF standard in some revision)

check with
which gmtinfo

3

use grdinfo with grid files

Doh. Apologies.
Was using “grdinfo” inside the script and “gmtinfo” outside.
All good now.
