Taking the first bit (i.e. even vs odd)

I need to read a binary data file with this information: 3600000 Samples, 8-Bits, Start Location: 112. I used the command '*uint8'.
But I have to take the first bit (i.e. even vs odd) to convert to binary 0-1 from each of the 1000 bytes. Then down sampling from 1000 to 200, by taking every 5th bit.
Can you help with that, please?

Why not take the last bit of every fifth byte, to begin with. For example, something like this
f = fopen('filename.bin', 'r');
data = fread(f, inf, '*uint8');
data_5 = data(1:5:end);
bits = rem(data_5, 2);
