Hi, Daniele --

I am able to read your station data with my build of GraDS 2.2.1. Here is the code that is issuing that error message:



/* Round varying dimensions 'outwards' to integral grid units. */

  for (i=0;i<5;i++) {

    if (i==pst->idim || i==pst->jdim) {

      dmin[i] = floor(dmin[i]+0.0001);

      dmax[i] = ceil(dmax[i]-0.0001);

      if (dmax[i]<=dmin[i]) {

        gaprnt (0,"Data Request Error: Invalid grid coordinates\n");

        snprintf(pout,1255,"  Varying dimension %i decreases: %g to %g\n",i,dmin[i],dmax[i]);

        gaprnt (0,pout);

        snprintf(pout,1255,"  Error ocurred getting variable '%s'\n",vnam);

        gaprnt (0,pout);

        return (NULL);

      }

    }

  }



This should only appear for gridded variables, but you are using station data. What is the output from ‘q file’? Does it say “Type = Station Data” ? Is there some weird white space in your ‘dtype station’ entry in the descriptor file?



Also, what is the output from ‘q dims’ ? Does it show X and Y as fixed?

    Dear GrADS Users,



    sorry for the long mail but the question is important for us.



    We have been using Open GrADS 2.0.1 on a Red Hat Enterprise Linux Server release 6.5

    since many years with excellent results.



    Now we are going to update both Linux server with Fedora 31 operating system

    and Open GrADS version 2.2.1.



    With Open GrADS 2.2.1 we aren't able to plot station time series

    of the attached files written in Fortran 90 language. They are located in Piedmont, north-western Italy.

    ==============================================================================================================



    grads -cl "open RETEA_PIEMO_20200810.ctl"



    Welcome to the OpenGrADS Bundle Distribution

                  --------------------------------------------



    For additional information enter "grads --manual".



    Starting "/usr/local/bin/Linux/Versions/2.2.1.oga.1/x86_64/grads   -cl 'open RETEA_PIEMO_20200810.ctl' " ...



    ga-> set t 1 last

    Time values set: 2020:8:10:0 2020:8:10:23

    ga-> set lat 45

    LAT set to 45 45

    ga-> set lon 8

    LON set to 8 8

    ga-> d t2m(stid=90139)

    Data Request Error: Invalid grid coordinates

      Varying dimension 1 decreases: 45 to 45

      Error ocurred getting variable 't2m'

      Error ocurred at column 1

    DISPLAY error:  Invalid expression

      Expression = t2m(stid=90139)



    =====================================================================================================================



    Instead with Open GrADS 2.0.1:

     grads -cl "open RETEA_PIEMO_20200810.ctl"



                  Welcome to the OpenGrADS Bundle Distribution

                  --------------------------------------------



    For additional information enter "grads -h".



    Starting "/opt/grads-2.0.1.oga.1/Contents/Linux/Versions/2.0.1.oga.1/x86_64/grads   -cl 'open RETEA_PIEMO_20200810.ctl' " ...



    ga-> set t 1 last

    ga-> set lon 8

    LON set to 8 8

    ga-> d t2m(stid=90139)

    ga->



    all is ok.



    Do you know which can be the problem?



    In the following rows you can see how we installed Open GrADS 2.2.1
