Thanks very much John for advice on writing biary to ASCII in grads. Actually I posed this question some time go and it is ok.<br>My recent question was whether one could access analysis and forecasts on nomads servers directly through grads.<br>

Hi all,<br>
<br>
I am trying to find out a minimum and a maximum of a variable.<br>
Therefore I use 'q attr' and will pars it.<br>
The problem is that the format is something like<br>
"evaporation Float32 data_range 4.73882e-25,454.459"<br>
I can get that line, but now I have a problem.<br>
I have no operation in GrADS to divide the last values right?<br>
I need to divide it into to strings/values to get separate min and max<br>
values.<br>
How can I do this? Or is there another easier way to get the min and the<br>
max values of a variable?<br>
<br>
Thank you,<br>
Simon<br>

hello,<br>
I am using the grads version 2.0.a9.oga.1.the netcdf file that opens<br>
correctly is<br>
<br>
SDF file C:\Users\acer\Desktop\sst\1998\<a href="http://mar98.nc" target="_blank">mar98.nc</a> is open as file 1<br>
LON set to 0.0219727 159.983<br>
LAT set to -70.9937 -20.0171<br>
LEV set to 0 0<br>
Time values set: 1998:2:15:0 1998:2:15:0<br>
E set to 1 1<br>
ga-> d sst<br>
Contouring: -0 to 30 interval 3<br>
<br>
<br>
When I create a ctl file as follows..<br>
<br>
dset C:\Users\acer\Desktop\sst\1998\%mc%<a href="http://y2.nc" target="_blank">y2.nc</a><br>
title SST, Pathfinder Ver 5.0, Day and Night, Global, Science Quality<br>
(Monthly Composite)<br>
options template<br>
tdef 1 linear 12Z16OCT1998 1dy<br>
zdef 1 linear 0 1<br>
xdef 3641 linear 0.0219727 0.0439453<br>
ydef 1161 linear -70.9937 0.0439453<br>
undef -1e+07<br>
vars 1<br>
sst 1 -999 Sea Surface Temperature<br>
endvars<br>
....the file opens.the time series also opens but the the contouring that I<br>
get is:<br>
"Contouring: -3e+38 to 3e+38 interval 5e+37"<br>
which is incorrect!<br>
What to do how to set the required limits??<br>

Hi Zilore<br>
I will try gxout print to list the value of grids, and then query the result and<br>
write out.<br>
'set gxout print'<br>
'd var'<br>
w=write(output_file,result)<br>
c=close(output_file)<br>
<br>
You can use query to separate the result as following:<br>
'set gxout print'<br>
'd var'<br>
length=subwrd(result,4)<br>
i=1;while(i<=9+length)<br>
value=subwrd(result,i)<br>
w=write(output_file,i)<br>
i=i+1;endwhile<br>
c=close(output_file)<br>
<br>
Just for sure you close the output file.<br>
<br>
Is this what you want?<br>
John<br>
