cif2hkl

## NAME

cif2hkl - cif2hkl

## SYNOPSIS

**cif2hkl** \[*options*\]\[*-o outfile*\] *file1 file2* ...

## DESCRIPTION

Action: Read a CIF/CFL/SHX/PCR crystallographic description

-

  and generates a HKL F^2 reflection list.

Input:

- file1...

  Input file in CIF, PCR, CFL, SHX, INS, RES format.

- The file format is determined from its extension

  .CIF           Crystallographic Information File
   .PCR/.CFL      FullProf file
   .SHX/.INS/.RES ShelX file

Output:

-

  a file with readable header, and reflection list with columns

-

  \[ H K L Multiplicity Sin(Theta/Lambda) d\_spacing \|F\|^2 \]

Options:

- **--help**, **-h**

  Show this help

- **--version**, **-v**

  Display program version

- **--out** FILE, **-o** FILE

  Specify the name of the next output file.
   Default is to add .hkl to the initial file name.

- **--lambda** LAMBDA, **-l** LAMBDA

  Set the incoming probe wavelength \[Angs\].
   Default is 0.5

- **--powder**, **-p**

  Generate a list of unique HKL reflections (for powders). Default.

- **--xtal**, **-x**

  Generate a list of all HKL reflections (for single crystals).

- **--mode** MODE, **-m** MODE

  Generate structure factors for given probe, where MODE is
   NUC=neutron(default) XRA=xrays ELE=electrons

- **--verbose**

  Display processing details.

- **--no-output-files**

  Just read the CIF/CFL/ShelX file (for checking).

Example: ./cif2hkl **--powder** **--mode** NUC **-o** CaF2.laz CaF2.cfl
