Python library for miscellaneous operations
Classes, methods and function for my own use in a PhD about crystallography
A collection of Python-code that I use/have been using for my work in neutron diffraction, molecular magnetism and as a TA in physical chemistry
crystalStructure-class does not save the Uiso-value from the cif-file when the Utype is Uani
It is a problem because generating a cry-file when occupancies are not 1 requires the Uiso-value to be put into the A-card
Example of problem
from cifoperations import cc
dbm = cc.crystalStructure('C:\Users\Emil\Documents\Uddannelse\PhD\pnd_susceptibility\magnetic_ellipsoids\DBM.cif')
Traceback (most recent call last):

Make it so that the "F XXm 3 ..." card is constructed automatically when the magnetic atom is a lanthanide
it looks like the function _read_symmop in cifoperations.symmetry is reading the symmetry element wrong when the translation is given before the rotation,
i.e.
x-1/2, -y-1/2, z-1/2 is being read correctly
but for
1/2+X,1/2-Y,1/2+Z,
the translational part is being returned as (0,0,0).
I think this will make it more intuitive and will also make it easier to allow for creating an empty class
there are multiple classes called crystalStructure under crystallography.py, crystallography_v1.0.py and cifoperations/crystalStructure.py
these should be combined
