I'm using dump.py from the pizza.py toolkit to parse LAMMPS dump files. My dump files are fairly big (2GB), and I was wondering if there was an easy way to have dump.py initially parse only every n-th (e.g. every 10-th would be convenient for me) or only parse some range of the dump file. It seems like the dump.tselect() time select function only relates to iterating over snapshots *after* they have initially been parsed.
Otherwise, it doesn't seem so hard for me to write my own parser; but this seems like it defeats the point of having some nice standard analysis tool like pizza.py.
