Hi Nicolas,
I left this print in R__unzip on purpose, just in case an unexpected
case
appears. We are aware of "academic" cases when the size of the file is
so short that there is nothing to unzip.
It is pretty clear that this is your case. Send me your file, I can
check,
if you like. Note that when this message appears, your data should be
OK.
It just means that you are in one exotic case that should not happen
with real data.
