I would come to the same conclusion ;)

Is there a chance you could share that dataset?  would make it easier to
figure out WTF

just do

h5save('/tmp/dataset.hdf5', avgds)

and make that file available online or in dropbox or whatever other
means... not sure if email would tollerate the size though but you could
try emailing it to debian at onerussian.com
