Hello, All:

I found that current version of grads do not well handle
the netcdf file with template option. When I use xdfopen to open
the ddf file as below

dset ^SOUT.%m2-%d2-00.nc
title 3D gaseous species
undef  -99999.0
options template
xdef COL 97 linear 1. 1.
ydef ROW 62 linear 1. 1.
zdef LAY 21 levels 7.25 25.40 54.5117 109.328 219.887 406.969 675.054
990.77 135
8.73 1828.5 2368.88 2942.16 3553.04 4207.36 4912.52 5678.06 6516.63
7527.75 8868
.97 10717.2 13153.4
* in GMT
tdef TSTEP 377 linear 00Z01JUL2004 3hr
vars 1
SO2=>so2 21 99 SO2 (ppbv)
endvars

The grads-1.8s111 has "Segmentation fault" (my linux machine uses
RedHat 7.3). The grads-1.9beta3 is "slightly" better as it can finish
'xdfopen', but "Segmentation fault" appeared again when I perform further
operation, like 'd ave(so2,t=1,t=300)'. I found that only
grads-1.7beta9 can handle all the issues, but this old version lacks of
some useful math functions. Does anybody know how to
solve this problem?

Thanks a lot
