Unpack an 8 bit unsigned char matrixby Ineffectual (Scribe)

Ineffectual has asked for the
wisdom of the Perl Monks concerning the following question:
I'm attempting to unpack an 8 bit unsigned char matrix that was generated in python. I'm not sure how to do this in perl. Here's what I've attempted so far.
This will print out:
reading file 05398.bin with size 90942 with nCols 3954 and nRows 23
nCols stays static for all of the files, but nRows changes for each file.
So this should come out to be a matrix that has 3954 columns and 23 rows.
I've tried using C$nCols or C$nRows in the split or b$nRows or B$nRows, but none seems to give the appropriate output. Each cell of the matrix should contain one number 0 or 1. I've tried splitting on length($read) or $nRows before unpacking. When I do an unpack('C*', $read) into an array then the # of elements is generally 5-6, not the length of my rows. I'm stumped- help perl monks!
