Stereo Signature Molecular Descriptor
Usage: sscan <file.mol> <output-type>
<file> is mol file
<output-type>
output types are (x is the diameter, any integer between 0 and 100000):
scanx: signature DAG
sscanx: stereo signature DAG (CIP rules)
fscanx: fast stereo signature mode
with scan and sscan output modes:
if x is omitted then the code will canonicalize the structure
and print the maximum signature (according to the invariant computed from the CIP rules).
with sig and ssig output modes:
if x is omitted, x takes the value 0
if x is greater than 12, x takes the value 12.
