At CCDC we are passionate about delivering continuous improvements to our scientific software and data to ensure our users are able to harness the power of over one million structures in the CSD through effective visualisation, analysis and extraction. Discover the latest developments of the CCDC software suites over the last 12 months.
2020.1 CSD Release (April 2020)
Aromatics Analyser in CSD-Materials
- The launch of the new Aromatics Analyser component in CSD-Materials, providing the ability to quickly and easily analyse the contribution of aromatic interactions to the stability of a crystal structure. This component is particularly effective when assessing pairs of crystal structures with the same hydrogen bonds, or with no hydrogen bonds at all. Read more.
CSD Pipeline Pilot Component Collection
First release of our CSD Pipeline Pilot Component Collection, this covers key capabilities for users to access CSD data and functionality through the popular workflow tool Pipeline Pilot including searching, model validation conformer generation and virtual screening. Read more.
Descriptors Module in the CSD Python API
We've greatly expanded the molecular descriptors available through the CSD Python API, we hope this expanded descriptor set is useful for our community to support on-going machine learning efforts generally, as well as those making direct use of CSD data. Read more.
New Portfolio Versioning
This release also introduces simpler versioning across the CSD Software Portfolio, to make it easier for our community, and our support conversations with you, we have introduced cross-portfolio versioning, so that it will be obvious which release each of your CSD products belongs to - in this case the 2020.1 CSD Release! Read more.
2020.0.1 CSD Release (February 2020)
This release includes a collection of smaller improvements to the CSD software portfolio.
A number of new molecular descriptors have now been made available within the descriptors module of the CSD Python API. We have made improvements to correct issues in certain user set-ups with Mercury on start-up, to ensure ConQuest can find CSD databases correctly and to ensure preferred orientation options can be seen in Mercury's Powder Pattern generation interface when appropriate. Fixes are also included for problems with DASH (when generating Z matrices) and with the command-line version of Mogul (used in some 3rd-party integrations to Mogul).
Please note that the command-line versions of Mogul and ConQuest (mogulbatch and cqbatch) are now deprecated and integration is recommended via the CSD Python API.
2020.0 CSD Release (December 2019)
In the last year we have seen the released CSD grow to over one million structures for the first time; a huge milestone in structural chemistry. The continued growth in data and the increasing diversity and complexity of new structures means that users can have more confidence in their results and gain even more insights from the database.
This year’s release:
- Takes the CSD to 1,016,168 unique structures (1,034,174 entries)
- Comprises over 60,000 entries new entries
- Includes over 5,000 new CSD Communications
- Targeted enhancements to existing CSD entries
- Read more about this data release
- Further optimisation of our GOLD protein ligand docking software for use in ultra-large docking projects including libraries of tens of millions of compounds, enabling the running of the GOLD docking algorithm using fast settings on cloud deployed computing systems, with automated selection of the best results based on user-defined requirements.
- Quick and easy hydrogen-bond likelihood analysis with new H-bond Coordination Quick-View, enabling the quick assessment of the likelihood of H-bond behaviour based on H-bond coordination numbers in the observed structure. Read more.
- The incorporation of Python 3 by default, meaning the CSD Python API is Python 3 enabled straight away at the point of installation and easy to integrate with other key scientific Python packages such as TensorFlow, scikit-learn, matplotlib, pandas and RDKit. Read more.
- The implementation of an entirely opt-in Product Telemetry system in our software which is able to capture information about which components have been used and on what kind of operating system, helping us to make better data-driven decisions to inform the direction of our software and ensure maximum value for you as a user. Find out more.
- The launch of a new licensing system which increases the flexibility of access to CSD data and software. The new system is a modern, secure and regularly updated third-party licensing system which enables both online and offline activation, allows use of any software release with a valid licence, and provides flexibility in length of licence. Read more.
2019.3 CSD Release (September 2019)
- 14,673 new entries
- This release brought the total size of the CSD to 1,023,815 entries and 1,006,180 unique structures, taking the CSD past one million structures for the first time!
- Read more about this data release.
- The launch of a new scripting interface that connects CCDC’s first class 3D substructure searching with searching of protein-ligand binding sites derived from the Protein Data Bank (PDB). This update enabled seamless interchange between searching CSD data and PDB data, allowing for the easy extraction of data driven insight from mining of 3D information including ligands with specific structures/similar structures, patterns of interactions between protein binding sites, waters, metals and small molecules, and geometric patterns within small molecules bound to proteins.
- This release also included stage one development of GOLD software to deliver a streamlined high throughput mode for ultra-large docking, enabling reduced output which will improve speed and disk space across many platforms.
CSD-Materials & CSD-Discovery
- The launch of molecular interaction maps in the CSD Python API enabling automated generation of interaction maps for protein binding sites, automated generation of interaction maps for small molecules, and easy integration of interaction maps with 3rd party tools.
- Polymer expansion in Mercury enabling much faster and more responsive expansion of polymeric, or networked, structures. Offers new options for more tailored expansion to explore structures the way you want to and easy pruning of structural views to generate high impact graphics and movies.
2019.2 CSD Release (May 2019)
- 14,702 new entries
- 14,140 new unique structure determinations
- Enables access to over one million entries through ConQuest searches, Mercury analyses and other knowledge-based research (note: that this release did not allow access to one million unique crystallographic structures).
- Read more about this data release.
- Support in the CSD Python API for all types of 3D query available in ConQuest.
- Extension of the CSD-CrossMiner database to include nucleic acid-containing structures from the PDB. Searching these structures was augmented by the addition of new, nucleotide specific feature definitions.
- Improvements enabling searching of the Protein Data Bank (PDB). This release provided a set of augmentations to the CSD Python API that make the software better at handling proteins. These changes mean that the same 3D queries can be constructed and run against individual protein structures.
2019.1 CSD Release (February 2019)
- Size of the CSD reaches over 977,000 unique structure determinations
- 20,808 new entries
- Read more about this data release.
- The launch of polyhedral display in Mercury, facilitating access to a simple, intuitive option for users to visualise metal-organic structures using polyhedral representations. The inclusion of a polyhedral display style, partnered with Mercury's structure exploration features and high-resolution image output using POV-Ray, make generating high-quality graphics for metal-organic structures effortless.
- The first release of the CSD Python API that is Python 3 compatible. Additional Python 3.7 packages are now available to download and install into your preferred Python environment.
