This usually means that no atoms were read in refmac.
If you look a few lines up you will see that 0 atoms were read in. 
That, in turn, means that 'reshuffle' which prepares you input
pdb file for warpNtrace produced an error (look at
My guess for that is that you PDB had no proper CRYST/SCALE cards.

...brk is a normal pdb file (from pdb at BRooKhaven days).
(?? for warpNtrace from a model you also needed a .brk file ...!)
As for protin, it is INput that is needed.
A bit of RTFM or look at the example file distributed 
with arp/warp can help.
