* 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
* Add AtomPDBResidueInfo during molops::addhs
* Test addhs and AtomPDBResidueInfo
* Little cleanup
* Fix serial
* Refactor code, add unique Hs labels
* Move code to separate function + bugfix.
* Make function optional (AddHs residueInfo param)
* Rename argument
* Add support for dative bonds to molfile reader plus writer and to SMILES reader (SMILES writer already supports it).
Initial V3000 molfile reader and writer dative bond support by Esben Jannik Bjerrum.
* first pass at adding -> as dative bond in smiles/smarts
more testing required
* all tests pass
* update .cmake files for lex
* patch from Roger Sayle to support nucleic acids as well as amino acids
* add some tests which do not yet pass
* fix a bug I introduced in residue name parsing
* basic sequence testing
* add some more tests
* Adds Atom atom map and rlabel apis
* Moves RLabels to their own namespace, adds other properties.
* Removes namespaces, liberally adds Atom to function names.
* move detail::computedPropName to RDKit::detail::computedPropName
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%)
