(spinw-nosym)=

# spinw.nosym method

## Syntax
  
`nosym(obj)`
  
## Description
  
`nosym(obj)` reduces the crystal symmetry to $P0$ but keeps all symmetry
generated atoms, that become all symmetry inequivalent. The function can
be used to test different types of symmetry breaking terms in the spin
Hamiltonian.
  
## Examples
  
The example generates an FCC cell using explicit translations. After
applying the `spinw.nosym` function, the `cryst.unit_cell.r` contains the
four generated atomic positions, that are not symmetry equivalent any
more.
 
```matlab
symOp = 'x+1/2,y+1/2,z;x+1/2,y,z+1/2;x,y+1/2,z+1/2'
cryst = spinw
cryst.genlattice('lat_const',[8 8 8],'sym',symOp,'label','FCC')
cryst.addatom('r',[0 0 0],'label','Atom1')
cryst.unit_cell.r
```
*Output*

## Input Arguments
  
`obj`
: [spinw](#spinw) object.
  
## Output Arguments
  
The `obj` input will have `obj.lattice.sym` field equal to zero and the
[obj.unit_cell] field will contain all the generated atomic positions.
