Name: atomic coordinates for the Mixed-Basis Pseudopotential (MBPP) code
Extension: none (the file must be named COORAT for use with MBPP)
Specification: N/A
Visualization programs: none
The supercell parameters are not specified in a COORAT file, but in the MBPP input file (INP). So, when reading a COORAT file, Atomsk will search for a file named INP in the current directory, and if it exists read the supercell parameters from it. Each supercell parameter may contain one special character (o, e, h...) and/or a star (*) indicating multiplication with a number (e.g. "0.5*h"); the slash sign (/) is not recognized. If no INP file is found then Atomsk automatically creates a bounding box (this is identical to the option -rebox) for compatibility with other output formats that require a supercell.
When writing to the COORAT format, Atomsk will attempt to write supercell parameters to the file called INP in the current directory. If this file already exists the user will be prompted whether to overwrite it or choose another name. Beware that this INP file is incomplete and is not fully set for a simulation.
atomsk my_system.xsf COORAT
This will read the file my_system.xsf, and convert it to the file COORAT.
