== Keywords for space group assignment == | == Keywords for space group assignment == | ||
If you know the space group and unit cell parameters of your crystal in advance you just need these two keywords: | |||

:If you don't know the space group, put six 0s or comment out the line. Unit cell parameters need to respect the constraints of the Laue group, e.g. all angles must be exactly 90.0 for orthorhombic and tetragonal space groups, a and b must be equal for trigonal and tetragonal, and so on. | :If you don't know the space group, put six 0s or comment out the line.

If you want to assign a space group and unit cell parameters to a crystal you most probably need this keyword as well: | |||
