[pymvpa] Multiple datasets in one hdf5 file

[孔令军]

Hi,
Thank you so much for the replies!! I now have 15 subject's datasets in one file, but seem to still be missing something.
(I had used the h5save('/tmp/out.h5', [ds1, ds2]) to make the one file consist of the 15 subjects. And can be loaded correctly) 
Working through the hyperalignment tutorial, after loading using h5load, zscoring the individual datasets or inserting subject IDs to the individual datasets doesn't work with my combined dataset file (missing some attributes). It definitely works when using the example hyperalignment dataset file though.The code and error display are showed at the end.
Pardon me for the repeated questions on this. Would anyone please let me  know if there is something I am neglecting to do before saving all the datasets into the one file? Thank you very much!
