[gradsusr] station data

[Pou-Chang John Chen]

The example Fortran code should be stream type, so the 'options sequential' in 
ctl file could be the problem.
If it doesn't work, here is an example to write station data in my site.

I think the most common mistake could be:
 1. the time should keep the same value, which means the report time. 
 2. the nlev should keep 1 as one layer surface data

Subject: [gradsusr] station data

Hi, 

I'm new grads user and i'm having problems with station data. 

i've created a .txt data with year month day station name and data 
value(precipitation) for 16 stations during 123 days 

 1876  10   1  PPP   41.2  -8.6     0
 1876  10   1  GGG   40.5  -7.2   0.4
 1876  10   1  CMM   39.0  -7.0     0
 1876  10   1  EEE   38.6  -7.9     0
 1876  10   1  LLL   37.1  -8.6     0
 1876  10   1  AHH   38.7 -27.2  17.6
 1876  10   1  PDD   37.8 -25.7  19.3
 1876  10   1  FFF   32.6 -16.9   1.6
 1876  10   1  LLL   38.7  -9.1     0
 1876  10   1  CCC   36.5  -6.3     0
 1876  10   1  BBB   38.9  -7.0     0
 ...
i've used the fortran code from here  
http://www.iges.org/grads/gadoc/aboutstationdata.html  addapted for my .txt file

and created the .ctl file 
DSET   C:\DISASTER\20CRen\dez_1876\dados\estacoes \stat.dat
TITLE  station data   
DTYPE  station
STNMAP C:\DISASTER\20CRen\dez_1876\dados\estacoes\stat.map
UNDEF   -999.    
options sequential   
TDEF    123 LINEAR 1OCT1876 1dy  
VARS    1
prec   0   99   pprecipitation     
ENDVARS



when i run stnmap -i stat.ctl in command line i have de error:

Processing time step 1
Invalid sation hdr found in station binary file
possible causes: invalid level count in hdr
                         descriptor file mismatch
                         file not station data
                         invalid relative time
                         invalid sequential format
levs = 256 flag 26312 time 3.5872e-43

Could someone help me please?!!
