input_file output_file
positional arguments:
input_file Input file name.
output_file Output file name.
options:
-v, -version Show the program's version and exit.
-h, -help Show this help message and exit.
-a Disregard existing chirality properties and determine
the chiralities from geometry if possible. Assume that
all chiralities are variable for enumeration purposes.
-g Ignore existing chirality properties and assign the
chiralities using geometry where possible. Do not
enumerate the newly determined chiralities.
-n <number> Generate up to this many stereoisomers.
-pat {0,1,2,3} Set the type of enforcement for combinations of chiral
atoms: 0 - no enforcement; 1 - enforce combinations
that should always be met (e.g. for bridging atoms in
norbornane); 2 - class 1 plus patterns which are
expected to be followed (e.g. conserved patterns of
chiralities in steriods); 3 - class 2 plus any
additional patterns in the database; The default is
class 2.
-retain Used with -a option. Ensure that the input chiral
properties are present in at least one output
structure.
-pat_keep_orig_off Turn off retention of original templates that fail to
specified patterns of chiral atoms.
-restrict_expansion Do not vary chiralities that are explicitly listed as
undefined in the input file.
-skip_bad During generation of specified number of
stereoisomers, skip all structures with bad chirality
combination.
-dont_vary_double_bonds
During generation of the specified number of
stereoisomers, do not vary double-bonds whose parity
is labeled as variable.
-vary_ring_anc <number>
Controls whether ring anc values are varied.
-label_specified_chiralities
Set b_st_SpecifiedChirality atom property for chiral
atoms with specified (rather than sampled) chirality.
-verb {0,1,2,3} controls MMERR level of reporting. 0: MMERR_FATAL -
only report errors; 1: MMERR_WARNING - only report
errors and warnings; 2: MMERR_INFO - report errors,
warnings, and processing information; 3: MMERR_DEBUG -
report errors, warnings, processing information, and
debugging information.
