Hi Marc,
Thanks again. That link is helpful. I was able to read in the data directly
using the path in the h5read_f. I use
INTEGER, dimension(12,96):: data_out
data_dims(1) = 12, data_dims(2) =96
CALL h5dread_f(dset_id,H5T_STD_I64BE , data_out, data_dims,
error) as the h5dump indicates DATA_TYPE as H5T_STF_I64BE.
But it does not read properly ( gives core dump). I compile on a x86_64
m/c gfortran.
GROUP "All_Data" {
GROUP "AMS-SDR_All" {
>> DATASET "BeamTime" {
>> DATATYPE H5T_STD_I64BE
>>
>> Gompie
