You can pass -l with numbers up to five, to raise the log level.
Whether the srzip input module has detailled messages about the
cause for rejecting the archive, I don't know off the top of my
head.

Of course you cannot have 16 probes in units of 1 byte size.
Make that unitsize=2 to match the 16 data bits per sample point.
Your script assumes that units are always full bytes (i.e. probes
are full multiples of eight). That's OK, just put a note
somewhere to remain aware. :) Folding odd numbers of bits
together is a little more involved.
Oh, and use binary mode for the files with sample data, for
improved portability.
