The program WYCKSPLIT calculates the splitting of the
Wyckoff position when the symmetry is reduced from one given by the group G
to one given by a group H which is a subgroup of G.
As an input data the program needs the numbers of both groups as given in the
International Tables for Crystallography, vol.A,
and the transformation matrix that relates the basis of the supergroup with that
of the subgroup.
If you do not know the numbers of the groups, use the buttons
[choose it] to select them from the table with the space
If you do not know the transformation relating both bases, use the link to the
other programs on the Bilbao Crystallographic Server to find it.
NOTE: If one of the groups you are interested in has more than one conventional settings,
and you do not want to use the
you can choose the setting from the table with space group numbers and symbols
by clicking over [choose it].
When all of the input data is complete, click on the button
[Show group-subgroup data] to see the list with the
Wyckoff positions of the group and select the one for which the splitting should
