Reading .h5 files into IDL

Hi all,

I got a problem with .h5 files and IDL. I am currently trying to read
data from my .h5 files into a GUI i created using IDL. May i know what
routines i could use for this? My .h5 file is of a matrix of 200x
200x60.

I think you will have better luck if you describe your
problem more explicitly. Otherwise, it looks like a
quagmire. :-)

Depends on how your .h5 file is structured and whether you know the
structure on beforehand. This is the simplest case:

file_id = H5F_OPEN(file)
; You know e.g. that the data is in the "groupname"
; group and the dataset is called "dataname"
data_id = H5D_OPEN(file_id, '/groupname/dataname')
data = H5D_READ(data_id)
H5D_CLOSE, data_id
H5F_CLOSE, file_id
