Compare Lattices with NIST*LATTICE

This page compares two lattices via the Converse-Transform Relational Analysis (V. L. Karen & A. D. Mighell, U.S. Patent 5,235,523) as implemented in computer program NIST*LATTICE, "A Program to Analyze Lattice Relationships" (Version of Spring, 1991) by Vicky Lynn Karen and Alan D. Mighell, National Institute of Standards and Technology, Materials Science and Engineering Laboratory, Gaithersburg, Maryland 20899. [V. L. Karen and A. D. Mighell, NIST Technical Note 1290 (1991)].

Compare two lattices via Converse-Transform Relational Analysis.

Input two unit cells to compare, as well as a tolerance factor. The input unit cells will be reduced prior to their comparison.

Centering (see below)
a b c alpha beta gamma P I F A B C R/H
Cell 1
Cell 2
Tolerance
Range of generated integers (1-10):
or to default values.

Centering options:
Pnone (Primitive)
IBody-centered
FFace-centered
AA-centered
BB-centered
CC-centered
R/HRhombohedral cell on hexagonal axes.
Note: use "P" for rhombohedral cells with a=b=c, alpha=beta=gamma
