* This makes assignStereochemistry cleanIt=True not remove CIS/TRANS
bond stereo chemistry that was manually added as described in issue #1614.
Incorrect CIS/TRANS stereochemistry will still be removed by
'cleanIt=true' if symmetry is detected. However, this symmetry
detection doesn't work in more complex pseudo-stereo chemistry cases:
bond stereo that depends on other bond stereo to break symmetry; and
bond stereo that depends on other atom stereo centers to break
symmetry. Test cases for these cases have been added ifdef'd in based
on USE_NEW_STEREOCHEMISTRY.
However, getting USE_NEW_STEREOCHEMISTRY to work in a copacetic way is
not trivial, I tried a little bit here to no avail. I'm leaving the
test cases checked in as they should be useful when we decide to make
the plunge into using Canon::chiralRankMolAtoms for symmetry detection
instead of the CIP ranks.
So this fixes at least the glaring issue of STEREOCIS and STEREOTRANS
being incorrectly removed by 'cleanIt=true' when it is indeed valid
stereo. The checks made for symmetry are rudimentary, but don't feel
complete.
* add another test; make what's being tested explicit
* test smiles generation and function when Hs have been added
* add a test that fails
* I think that it's ok to remove this
* backup
* At this point all tests pass.
Bond wedging is now handled even if sanitization is turned off when mol files are read
* adjust to code changes
* fix a couple problems caused by rebase
* update docs
* Fixes#1735
I’m unsure if this is the correct solution, it appears
empty molecules never initialize their rings.
* Return immediately when ranking empty molecules
* Make github issue the correct one
* Always resize results to the number of atoms
* auto generate coords in mol block writer if includeChirality = True
* default to include chirality when writing mol blocks/files
* make isomeric smiles the default; note that not all tests are passing at the moment
* update a reaction test
* update expected cartridge search results
at this point all python, c++, and cartridge tests pass
* docs
* update incompatibility docs
* update doctests
* these now build
* minor example update
* update expected c++
* typo
* make allowCXSMILES=true the default
* add auto perception of chirality when reading 3D structures from mol blocks
* explain changes in release notes
* further doc update
* move detectBondStereoChemistry() into MolOps
* switch more code over to using the new function
* add an addStereoChemistryFrom3D() function. Needs testing still.
* add some tests
* cleanups and rename
o rdkit gains a RDKit::common_properties namespace that contains common string value properties
o Dict.h and below gain getPropIfPresent that attempts to retrieve a property and returns
true/false on success or failure. This is used to optimize access.
o rdkit learns how to pass property keys by reference, not value.
A new namespace has been added to RDKit, common_properties
that contains the std::string values for commonly used
properties. This helps to avoid typos in string values
but also avoids a creation of std::strings from character
values. All accessors (has/get/clear and getPropIfPresent) now pass
the key by reference.
Additionally, getPropIfPresent removes the double lookup
of hasProp/getProp which can be a significant speedup
in the smiles and smarts parsers (10-20%)
