Load data from 'broken' HDF5 file

Hi

During an EEG expeirment, my recording computer crashed and left the .HDF5-file containing the data 'broken'.

I've tried h5read and different variations thereof, but the file cannot be read, however I can read the data 'manually' using:

fid = fopen(broken_datafile);
dat = fread(fid,[1, 1000], 'uint8');
char(dat)

This nicely gives me the header information (about 40000 characters) and a some non-interpretable output, that I assume is related to teh recorded data:

Does anyone know if I can manually reconstruct the 16-channel EEG of inter type single + the trigger signal using the above approach? And how I can do it?
