newbie: trying to print ann average vertical profile numbers at specific lat, lon for monthly gridded binary file

[Steve Piper]

Hi,

I just started using Grads.  Great program!

I would like to write out in ascii, the annual average vertical
profile at
all 9 levels at a specified location (lat and lon) in
the grid for variable bioa.

I am reading a gridded data file that was written with Fortran
statement declaration

     real x(72,44,9,12,26)     ! lon, lat, levels, months, variables

My ctl file is:

      DSET      /Users/piper/Grads-test/CSU.gurney.L1.mmean.le.3D
    *    fortran sequential file  c(72,44,9,12,26)
   *                                lon lat lev month tracer
    *     sequential means fortran binary with record length integers
in record
    *     otherwise would use stream or direct access
    *     SUN is big-endian (had to swap to make it so with zz.f)
   *   OPTIONS big_endian for SUN, mac powerpc?
      OPTIONS sequential
   *  input file is from little_endian machine
      OPTIONS little_endian

set lon -180 180    # default is 0 360 when I issue q dim
set lat -86 86    # this was the default
set lev 1000 100   # default was 1000
set t 1 12              # default was t 1

q dim

Default file number is: 1
X is varying   Lon = -180 to 180   X = 1 to 73
Y is varying   Lat = -86 to 86   Y = 1 to 44
Z is varying   Lev = 1000 to 100   Z = 1 to 9
T is varying   Time = 00Z16JAN1994 to 00Z16DEC1994  T = 1 to 12
E is fixed     Ens = 1  E = 1

Not sure how to produce annual average array newbioa(72,44,9) from
bioa(72,44,9,12)

Tried this:

define newbioa =  ave(bioa,t=1,t=12)

It gives 108 lines (=9 x 12) of output stating
Averaging.  dim = 3, start = 1, end =12

ga-> q dim

d gr2stn(newbioa,60.75,89.38)
Operation error: Invalid dimension environment
Too many varying dimensions

set t 1

d gr2stn(newbioa,60.75,89.38)
Operation error: Invalid dimension environment
Looping dimension does not vary

Not sure why the gr2stn statements do not work.  Help?
Am I on the right track?

Thanks!
