 NAME
CRYSTAL – Read the cell parameters defining the shape of the simulation box

 SYNOPSIS
CRYSTAL $a$   [$b$   $c$  [ $\alpha$   $\beta$   $\gamma$]]

 DESCRIPTION
The arguments $\alpha$, $\beta$ and $\gamma$ to this command are defined using the usual crystallographic conventions: $\alpha$ is the angle between the $b$ and $c$ axis, $\beta$ is the angle between $a$ and $c$, and $\gamma$ is the angle between $a$ and $b$.

 EXAMPLES
CRYSTAL 12.3 14.5 12.3 90.0 95.0 90.0
CRYSTAL 15.0

 DEFAULTS
$\alpha=\beta=\gamma=90.0$
