Re: [Rdkit-devel] 2021.03.1 RDKit Release

[Rex D. <RD...@me...>]

HI, We are having problems with this release on Windows, and we need to fall back to the last version.  We have a tight deadline and don't have resources to investigate the error at this moment.  However, none of these seem to work:

C:\NewCompoundElucidation\elucidation>conda install -c conda-forge --revision 2020.09.1

CondaValueError: expected revision number, not: '2020.09.1'


C:\NewCompoundElucidation\elucidation>conda install -c conda-forge --revision Release_2020.09.1

CondaValueError: expected revision number, not: 'Release_2020.09.1'


C:\NewCompoundElucidation\elucidation>conda install -c conda-forge --revision v2020.09.1

CondaValueError: expected revision number, not: 'v2020.09.1'

(I also tried .01 instead of .1)

Can anyone advise me how to do this?

BTW I think the error is related to recent changes in pillow.  We draw literally thousands of molecules in a run, so it's hard to pin down without a good bit of effort. This is the error:

Fail to allocate bitmap
ORA-24550: signal received: Unhandled exception: Code=80000003 Flags=0

Subject: [Rdkit-devel] 2021.03.1 RDKit Release

Dear all,

I'm pleased to announce that the 2021.03 version of the RDKit is released. We actually managed to get the .03 release done during March. Shocking! ;-)
The release notes are below.[1]

The release files are on the github release page:
https://github.com/rdkit/rdkit/releases/tag/Release_2021_03_1<https://nam11.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Frdkit%2Frdkit%2Freleases%2Ftag%2FRelease_2021_03_1&data=04%7C01%7Crdwyer%40metabolon.com%7C25962483677c4f9373fa08d8f069e864%7C7fb8e81b6c5d4bfea0e2bab63ea5e1c5%7C0%7C0%7C637523684980670653%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=7qJHhYMlVm7N35WYYuPso4CkshXLNqRI05OBAU%2F7J3A%3D&reserved=0>

I do not plan to do conda builds for the Python wrappers in the rdkit channel for this release. The builds done as part of the conda-forge project are automated and cover more Python versions and operating systems than I could ever hope to do manually.
Please install the rdkit using conda-forge:
conda install -c conda-forge rdkit
I believe that the conda-forge builds of the new version should appear over the next couple of days.

I hope to finish the conda builds of the PostgreSQL cartridge for linux and the mac and have them available in the rdkit channel by later today or tomorrow.

Thanks to everyone who submitted code, bug reports, and suggestions for this release!

Please let me know if you find any problems with the release or have suggestions for the next one, which is scheduled for September/October 2021.

Best Regards,

# Release_2021.03.1
(Changes relative to Release_2020.09.1)

## Backwards incompatible changes
- The distance-geometry based conformer generation now by defaults generates
  trans(oid) conformations for amides, esters, and related structures. This can
  be toggled off with the `forceTransAmides` flag in EmbedParameters. Note that
  this change does not impact conformers created using one of the ET versions.
  (#3794)
- The conformer generator now uses symmetry by default when doing RMS pruning.
  This can be disabled using the `useSymmetryForPruning` flag in
  EmbedParameters. (#3813)
- Double bonds with unspecified stereochemistry in the products of chemical
  reactions now have their stereo set to STEREONONE instead of STEREOANY (#3078)
- The MolToSVG() function has been moved from rdkit.Chem to rdkit.Chem.Draw
  (#3696)
- There have been numerous changes to the RGroup Decomposition code which change
  the results. (#3767)
- In RGroup Decomposition, when onlyMatchAtRGroups is set to false, each molecule
  is now decomposed based on the first matching scaffold which adds/uses the
  least number of non-user-provided R labels, rather than simply the first
  matching scaffold.
  Among other things, this allows the code to provide the same results for both
  onlyMatchAtRGroups=true and onlyMatchAtRGroups=false when suitable scaffolds
  are provided without requiring the user to get overly concerned about the
  input ordering of the scaffolds. (#3969)
- There have been numerous changes to `GenerateDepictionMatching2DStructure()` (#3811)
- Setting the kekuleSmiles argument (doKekule in C++) to MolToSmiles will now
  cause the molecule to be kekulized before SMILES generation. Note that this
  can lead to an exception being thrown. Previously this argument would only
  write kekulized SMILES if the molecule had already been kekulized (#2788)
- Using the kekulize argument in the MHFP code will now cause the molecule to be
  kekulized before the fingerprint is generated. Note that becaues kekulization
  is not canonical, using this argument currently causes the results to depend
  on the input atom numbering. Note that this can lead to an exception being
  thrown. (#3942)
- Gradients for angle and torsional restraints in both UFF and MMFF were computed
  incorrectly, which could give rise to potential instability during minimization.
  As part of fixing this problem, force constants have been switched to using
  kcal/degree^2 units instead of kcal/rad^2 units, consistently with the fact that
  angle and dihedral restraints are specified in degrees. (#3975)

## Highlights
- MolDraw2D now does a much better job of handling query features like common
  query bond types, atom lists, variable attachment points, and link nodes. It
  also supports adding annotations at the molecule level, displaying brackets
  for Sgroups, rendering the ABS flag for stereochemistry, and a new "comic"
  mode.
- There are two new Contrib packages: NIBRStructureFilters and CalcLigRMSD
- There have been a number of improvements made to the R-Group Decomposition
  code which make it both more flexible and considerably faster

## Contrib updates:
  - Added NIBRStructureFilters: a set of substructure filters for hit-list triaging together with python code for applying them. The filters are described in the publication https://dx.doi.org/10.1021/acs.jmedchem.0c01332<https://nam11.safelinks.protection.outlook.com/?url=https%3A%2F%2Fdx.doi.org%2F10.1021%2Facs.jmedchem.0c01332&data=04%7C01%7Crdwyer%40metabolon.com%7C25962483677c4f9373fa08d8f069e864%7C7fb8e81b6c5d4bfea0e2bab63ea5e1c5%7C0%7C0%7C637523684980690647%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=jPSdvNWs8Z7lrd1iGQ37axHn3SOB4gbPkicK9739nxI%3D&reserved=0>
