in thread Unpack an 8 bit unsigned char matrix

I apologise. I omitted an essential part of the first unpack template (the repeat *). Please try substituting this:

my @matrix = map[ unpack 'C*', $_ ], unpack '(a' . NCOLS . ')*', $buff +er;
The template has become: '(a3954)*' which tells unpack to split the buffer into as many 3954-byte chunks as are available.

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
