## Option: remove-property

#### Syntax

`-remove-property <property>`

`-rmprop <property>`

#### Description

This option removes one or all auxiliary properties associated with the atoms.

The value of <property> should correspond to a property that was read from the input file, or set up with the option `-properties`. If <property> is "all" then all auxiliary properties are deleted.

If a selection was defined (with the option `-select`) then the property is not removed. Instead the property is set to zero for selected atoms.

#### Default

By default the auxiliary properties are not deleted, but they are written into files only when their format supports it.

#### Examples

- `atomsk system.cfg -rmprop all xsf`

  This will read the file `system.cfg` and convert it to `system.xsf`, removing all auxiliary properties (if any).

- `atomsk system.lmc -rmprop fx -rmprop fy -rmprop fz exyz`

  This will read the file `system.lmc` and remove the three components of the forces `fx,fy,fz`.
