Your inquiry here sounds less like a question about the HDF Library and more of a question about an application-specific use of HDF5; 2-channles, intermixed, odd/even, physiological measures, g.tec device etc. all sound like these are more related to the application than to HDF5 library proper. So, even though I am totally ignorant of the use case, it certainly smells and sounds to me like its independent of the HDF5 file format.
OTOH, sounds like you are somehow using a 32-bit floating point little endianne dataset to encode a 2-channel (16 bit/channel) signal. Is that right? Why use a floating point format for that though? Why not use one of the 32-bit integer formats? I'd be concerned you could too easily create NANs if you construct a 32-bit float using 2 arbitrary 16-bit values.

So even values correpond to the first channel and odd to the second. So far so good, however, the mean values of each channel do not correspond to valid physiological measures. So I'm looking for the value (or algorithm) allowing to reajuste the values for each channel, but wasn't able to find it. Do the value transformation for each channel is always the same for H5T_IEEE_F32LE when storing two channels or this is determined in the g.tec device and so is independent of the hdf5 file format? Some help will be welcome, many thanks! Florian
