rmatrix: Display unit cell from a .rmat file

"rmatrix" can read a ".rmat" file (See format description) and display the associated unit cell.

Usage:

rmatrix [filenames and options]

Without any arguments, the "rmatrix" program will look for the most recent ".rmat" file in the current directory, and display the unit cell associated with this. The unit cell will be standardized as well (If a transformation is given in the .rmat file, it will be applied. If none is given, the conventional unit cell will be derived by the algorithm of Y. Le Page).

A specific ".rmat" file can be given on the command line to get the information from that ".rmat" file instead of the most recent one.

Options include:

nostandardize: Do not standardize the unit cell, use the original setting.
transformed: Show the transformed/standardized reciprocal axis matrix instead of the reduced one.
notransformtrigonal: Keep trigonal cells in primitive setting, do not transform to hexagonal. The resulting unit cell can be used for symmetry relations (it is much easier to specify the asymmetric unit in the primitive setting).
showpg: List all valid point groups for the cell.
axcrit=##: Use the given axis criterium for the cell standardization. By default it will use the same value as has been used before in any cell reduction, or if none has been specified ever, 0.2 degrees. If this criterium is increased, higher symmetry will be generated more easily.
write=name.rmat: Write the resulting standardized cell to a new .rmat file named "name.rmat".
