Aligning Molecules Based on Substructure Search

A program that aligns the molecules based on a substructure search initialized with the given SMARTS pattern.

Command Line Interface

A description of the command line interface can be obtained by executing the program with the –help argument.

prompt> smartsalign2D --help

Will generate the following output:

Simple parameter list
input/output options :
   -in : Filename of input molecules
   -out : Output filename
   -smarts : SMARTS for alignment match
