* (at -NEWPSOFF option is not supplied) 2D stereo interpretation: *
* only bonds that have sharp end pointing to the stereogenic atom are *
* considered as being out of plane and only sharp ends of *
* INCHI_BOND_STEREO_SINGLE_?EITHER bonds are considered to determine *

0D Stereo Parity and Type definitions
*******************************************************************
Note:
=====
o Below #A is the ordering number of atom A, starting from 0
o See parity values corresponding to 'o', 'e', and 'u' in
inchi_StereoParity0D definition below)
=============================================
stereogenic bond >A=B< or cumulene >A=C=C=B<
=============================================
neighbor[4] : {#X,#A,#B,#Y} in this order
X central_atom : NO_ATOM
\ X Y type : INCHI_StereoType_DoubleBond
A==B \ /
\ A==B
Y
parity= 'e' parity= 'o' unknown parity = 'u'
Limitations:
============
o Atoms A and B in cumulenes MUST be connected by a chain of double bonds;
atoms A and B in a stereogenic 'double bond' may be connected by a double,
single, or alternating bond.
o One atom may belong to up to 3 stereogenic bonds (i.g. in a fused
aromatic structure).
o Multiple stereogenic bonds incident to any given atom should
either all except possibly one have (possibly different) defined
parities ('o' or 'e') or should all have an unknown parity 'u'.
Note on parities of alternating stereobonds
===========================================
D--E
In large rings (see Fig. 1, all // \\
atoms are C) all alternating bonds B--C F--G
are treated as stereogenic. // \\
To avoid "undefined" bond parities A H
for bonds BC, DE, FG, HI, JK, LM, AN \ /
it is recommended to mark them with N==M J==I
parities. \ /
L==K Fig. 1
Such a marking will make
the stereochemical layer unambiguous
and it will be different from the B--C F--G
stereochemical layer of the second // \\ // \\
structure (Fig. 2). A D--E H
\ /
N==M J==I
By default, double and alternating \ /
bonds in 8-member and greater rings L==K Fig. 2
are treated by InChI as stereogenic.
=============================================
tetrahedral atom
=============================================
4 neighbors
X neighbor[4] : {#W, #X, #Y, #Z}
| central_atom: #A
W--A--Y type : INCHI_StereoType_Tetrahedral
|
Z
parity: if (X,Y,Z) are clockwize when seen from W then parity is 'e' otherwise 'o'
Example (see AXYZW above): if W is above the plane XYZ then parity = 'e'
3 neighbors
Y Y neighbor[4] : {#A, #X, #Y, #Z}
/ / central_atom: #A
X--A (e.g. O=S ) type : INCHI_StereoType_Tetrahedral
\ \
Z Z
parity: if (X,Y,Z) are clockwize when seen from A then parity is 'e',
otherwise 'o'
unknown parity = 'u'
Example (see AXYZ above): if A is above the plane XYZ then parity = 'e'
This approach may be used also in case of an implicit H attached to A.
=============================================
allene
=============================================
X Y neighbor[4] : {#X,#A,#B,#Y}
\ / central_atom : #C
A=C=B type : INCHI_StereoType_Allene
Y X
| |
when seen from A along A=C=B: X-A Y-A
parity: 'e' 'o'
parity: if A, B, Y are clockwise when seen from X then parity is 'e',
otherwise 'o'
unknown parity = 'u'
Example (see XACBY above): if X on the diagram is above the plane ABY
then parity is 'o'
Limitations
===========
o Atoms A and B in allenes MUST be connected by a chain of double bonds;
How InChI uses 0D parities
==========================
1. 0D parities are used if all atom coordinates are zeroes.
In addition to that:
2. 0D parities are used for Stereobonds, Allenes, or Cumulenes if:
2a. A bond to the end-atom is shorter than MIN_BOND_LEN=0.000001
2b. A ratio of two bond lengths to the end-atom is smaller than MIN_SINE=0.03
2c. In case of a linear fragment X-A=B end-atom A is treated as satisfying 2a-b
0D parities are used if 2a or 2b or 2c applies to one or both end-atoms.
3. 0D parities are used for Tetrahedral Atoms if at least one of 3a-c is true:
3a. One of bonds to the central atom is shorter than MIN_BOND_LEN=0.000001
3b. A ratio of two bond lengths to the central atom is smaller than MIN_SINE=0.03
3c. The four neighbors are almost in one plane or the central atom and
its only 3 explicit neighbors are almost in one plane
Notes on 0D parities and 'undefined' stereogenic elements
=========================================================
If 0D parity is to be used according to 1-3 but CH3 CH3
has not been provided then the corresponding \ /
stereogenic element is considered 'undefined'. C=CH
/
For example, if in the structure (Fig. 3) H
the explicit H has been moved so that it Fig. 3
has same coordinates as atom >C= (that is,
the length of the bond H-C became zero)
then the double bond is assigned 'undefined' CH3 CH3
parity which by default is omitted from the \ /
Identifier. CH=CH
However, the structure on Fig. 4 will have double Fig. 4
bond parity 'o' and its parity in the Identifier is (-).
Notes on 0D parities in structures containing metals
====================================================
Since InChI disconnects bonds to metals the 0D parities upon the
disconnection may change in several different ways:
1) previously non-stereogenic bond may become stereogenic:
\ / \ /
CH==CH disconnection CH==CH
\ / ======>
M M
before the disconnection: after the disconnection:
atoms C have valence=5 and the double bond may become
the double bond is not stereogenic
recognized as stereogenic
2) previously stereogenic bond may become non-stereogenic:
M M(+)
\ / /
N==C disconnection (-)N==C
\ ======> \
3) Oddball structures, usually resulting from projecting 3D
structures on the plane, may contain fragment like that
depicted on Fig. 5:
M A M A
|\ / B / B
| X / disconnection / /
|/ \ / ======> / /
C===C C===C
Fig. 5
(X stands for bond intersection)
A-C=C-B parity is A-C=C-B parity is
trans (e) cis (o) or undefined
because the bond because C valence = 3,
orientation is same not 4.
as on Fig, 6 below:
A M
\ / Removal of M from the structure
C===C on Fig. 5 changes the geometry from trans
/ \ to cis.
M' B Removal of M and M' from the structure
Fig. 6 on Fig. 6 does not change the A-C=C-B
geometry: it is trans.
To resolve the problem InChI API accepts the second parity
corresponding to the metal-disconnected structure.
To store both bond parities use left shift by 3 bits:
inchi_Stereo0D::parity = ParityOfConnected | (ParityOfDisconnected<<3)
In case when only disconnected structure parity exists set
ParityOfConnected = INCHI_PARITY_UNDEFINED.
This is the only case when INCHI_PARITY_UNDEFINED parity
may be fed to the InChI.
In cases when the bond parity in a disconnected structure exists and
differs from the parity in the connected structure the atoms A and B
should be non-metals.

GetINCHI / GetStdINCHI
inchi_Input is created by the user; strings in inchi_Output are allocated and deallocated by InChI
inchi_Output does not need to be initilized out to zeroes; see FreeNCHI()/FreeSTDINCHI() on how to deallocate it
Valid options for GetINCHI:
(use - instead of / for O.S. other than MS Windows)
Structure perception (compatible with stdInChI)
/NEWPSOFF /DoNotAddH /SNon
Stereo interpretation (lead to generation of non-standard InChI)
/SRel /SRac /SUCF /ChiralFlagON /ChiralFlagOFF
InChI creation options (lead to generation of non-standard InChI)
/SUU /SLUUD /FixedH /RecMet /KET /15T
GetINCHI produces standard InChI if no InChI creation/stereo modification options
are specified. Inveresely, if any of SUU/SLUUD/RecMet/FixedH/Ket/15T/SRel/SRac/SUCF
options are specified, generated InChI will be non-standard one.
GetStdINCHI produces standard InChI only.
The valid structure perception options are:
/NEWPSOFF /DoNotAddH /SNon
Other options are:
/AuxNone Omit auxiliary information (default: Include)
/Wnumber Set time-out per structure in seconds; W0 means unlimited
In InChI library the default value is unlimited
/WMnumber Set time-out per structure in milliseconds; WM0 means unlimited
In InChI library the default value is unlimited
/OutputSDF Output SDfile instead of InChI
/WarnOnEmptyStructure
Warn and produce empty InChI for empty structure
/SaveOpt Save custom InChI creation options (non-standard InChI)

InChIKey API
InChIKey description
The InChIKey is a character signature based on a hash code of the InChI string.
Standard InChIKey is produced out of standard InChI.
Non-standard InChIKey is produced out of non-standard InChI.
AAAAAAAAAAAAAA-BBBBBBBBCD-P
InChIKey layout is as follows:
AAAAAAAAAAAAAA
First block (14 letters)
Encodes molecular skeleton (connectivity)
BBBBBBBB
Second block (8 letters)
Encodes tautomers, stereochemistry, isotopomers, reconnected layer
C
'S' for standard
'N' for non-standard
D
InChI version ('A' for 1)
P - (de)protonation flag
Protonization encoding:
N 0
O +1 P +2 Q +3 R +4 S +5 T +6 U +7 V +8 W +9 X +10 Y +11 Z +12
M -1 L-2 K -3 J -4 I -5 H -6 G -7 F -8 E -9 D -10 C -11 B -12
A < -12 or > +12
All symbols except delimiter (dash, that is, minus) are uppercase English
letters representing a "base 26" encoding.
