Re: [Wien] Role of sgroup program

2013-06-24 Thread Peter Blaha
Some spacegroup have "2 different settings" (the origin of the cell is shifted to another position). Wien2k requires a setting WITH inversion symmetry at the origing and sgroup will do this for you in case of a spinel-structure. Other structures do not have this problem with settings and it i

Hello Saurabh, Sgroup will try to find the smallest primitive cell by maximizing the symmetry. This gives you the same structure. Since this lowers the amount of inequivalent positions it does reduce the freedom (so if you want to give one of them a slight nudge and break the symmetry you ma

[Wien] Role of sgroup program

Dear Peter Blaha & WIEN2k users, I am using WIEN2k 12.1 version. During initialization through w2web while viewing outputsgroup we can accept either the case.struct file generated by sgroup (which changes the position coordinates of the atoms in the primitive cell) or keep our original file. Accord
