Hi everyone,
i'm new to netcdf. I've read this is a generic ml in which one can post
problems. This is a problem with the use of the method "public float[]
readData(RandomAccessFile raf) throws IOException" of
"ucar.nc2.grib.grib1.Grib1Record".
I have this simple method for records debug:
private void recordsDebug(List<Grib1Record> grib1Records, Formatter f){
if(grib1Records!=null){
if(grib1Records.size()!=0){
f.format("%s%n", "size: "+grib1Records.size()+"\n");
for (Grib1Record grib1Record : grib1Records) {
ucar.unidata.io.RandomAccessFile raf = null;
try {
raf = new
ucar.unidata.io.RandomAccessFile(fileName, "r");
raf.order(ucar.unidata.io.RandomAccessFile.LITTLE_ENDIAN);
float values[] = grib1Record.readData(raf);
for (float value: values){
f.format("%f%n", value);
}
} catch (IOException e) {
e.printStackTrace();
} finally {
if (raf != null)
try {
raf.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
else {
f.format("%s%n", "size: "+grib1Records.size()+"\n");
}
}
else {
f.format("%s%n", "No records!\n");
}
}
This method gives me EOFException:
java.io.EOFException

The file i'm trying to read is a grib-1 file, and i actually can read it
with ToolsUI. The file contains only two variables:
(50) v-component of current
and (49) u-component of current
and ToolsUI detect many 'Nan'-values when i try to read variable values in
Iosp->GRIB1->GRIB1Collection->Grib1Record(Panel)->ShowData(Option).
If it does some difference, the GRIB1-file i'm taking about is called
"<something><suffix>.grib" where suffix is:
2013092600_t000 and the parameters section contains a reference time of
"2013-09-26T00:00:00Z" with a list containing only one TimeCoord:
//result of timecoord.tostring
timeCoord: type=integers timeUnit=1 Hour runDate=
2013-09-26T00:00:00Z
3, units (1 Hour) since 2013-09-26T00:00:00Z
From these symptoms, can i argue that this file is corrupted?
Thank you for your kind indications,
Teresa Noviello
