NAME

ase-db - Put stuff into or query database

SYNOPSIS

ase-db db-name [selection] [options]

DESCRIPTION

Selecton is a comma-separated list of selections where each selection is of the type "ID", "key" or "key=value". Instead of "=", one can also use "<", "<=", ">=", ">" and "!=" (these must be protected from the shell by using quotes). Special keys: id, user, calculator, age, natoms, energy, magmom, and charge. Chemical symbols can also be used to select number of specific atomic species (H, He, Li, ...).
