Thanks Matt.

All correct.

FWIW, I used the program ffmpeg on Linux to expand the files as I can then do the whole lot in one command and just leave it to get on with it. Probably I should create a Makefile or a smarter script to manage that process, so that it only expands files that aren't already expanded. I'm fairly sure PGM use libffmpeg internally to do similar.
