Information for Participants
Thank you to all those who participated in and submitted data to the 7th CSP Blind Test. We will be in touch via email following the final deadline regarding updates on results analysis and next steps.

Useful Information and Files
- Entry information and rules (only available to registered participants – please contact us if you require another copy of this document)
- Key dates and deadlines PDF
- CSP CIF preparation materials;
- Submission Summary – this is the main document containing details about the accompanying files, and instructions on how to complete them.
- CSP Dictionary – tabulated CSP CIF dictionary outlining the definitions, allowed values, units, and examples for each data field
- Dictionary file (.dic) – a file to be used with the enCIFer program to edit CIF files -instructions are in the main document
- CIF syntax information
- Example files (.zip) – an example of how a completed CIF folder should look like, based on a fictional example.
- Template files (.zip) – a folder containing templates that must be edited by participants to include in each submission.
Reminder: Group Name Identifier
Each participant group/team must have a unique group name identifier for labelling all files and folders for each Blind Test submission. The following guidance requires this identifier for various file names.
A suggested identifier for a group is the first initial and last name of the group lead. For example, for a participant group led by Jason Cole, the group identifier would be ‘JCole’.
This must be consistent throughout all the team submission files.
Submission 1 (now closed)
The deadline for submission 1 was 27 October 2021.
Submission 2 – (now closed)
Lists of structures (of length 100 or 500 depending on the target compound) have been provided to all registered participants via email on 13th December 2021. Re-ranked structures must then be submitted back to the CCDC by 14th June 2022.
Folder contents:
-
Either 100 or 500 CIF files (dependant on the target compound)
-
X_CSPBT7_method_summary.cif (X = group name identifier)
-
X_CSPBT7_structure_specific_data.csv (where X = group name identifier)
Data requirements for each material:
Please refer to the CSP CIF preparation materials for guidance on the completion of X_CSPBT7_method_summary.cif and X_CSPBT7_structure_specific_data.csv.
| Material | Required data (if applicable to your CSP methodology) | Strongly encouraged data |
| 100/500 CIF files |
Each .CIF must contain:
|
|
| X_CSPBT7_structure_specific_data.csv |
|
|
|

How/Where to Submit Results
Participants must complete tasks 1 and 2 outlined below per target (e.g. If you submit a list of structures for 4 different target compounds, you must complete the process 4 times)
By submitting results, all submission authors agree to all terms and conditions outlined in ‘entry_information_cspbt7.pdf’. Please contact us if you require another copy of this document.

FAQs
We plan to release the crystal structures via the CSD sometime after the final deadline (14 June).
However, we are unable to specify an exact date as we will be working with the experimental data providers to ensure correct permissions are granted where needed. It is also noted that there is a patent associated with Target compound XXX (co-crystal), and so the date for release of this data is beyond our control.
Following the submission 2 deadline (14 June):
14-21 June – a 1-week “grace period”, where groups who have submitted results may make any changes to the files they have submitted.
21 June – we will send out confirmation emails to all groups who have submitted results to confirm the details of the files received.
21-24 June – CCDC will be requesting any major corrections needed to the data. Participants will have 2 weeks to complete and send any corrections.
08-15 July – CCDC will send all participants (as long as no requested corrections are outstanding) a summary containing results from submission 1 and 2.
Once all groups have been sent their results (following all corrections made), we will release an anonymised summary of all results for all groups to all those who submitted data.
The “Rank” refers to that determined by relative energy at zero temperature. If temperature corrections are applied, the “Free energy rank” refers to the rank determined by relative free energy, and a temperature must be specified in the “Temperature” field.
We ask that the original structure name we provided is kept within the name, but you may add to the name an internal identifier or name. This will ensure we know the origin of the structure if optimisation methods have been used.
The final ranking of the structures should be based on your optimised structures, even if they no longer resemble the original. However, please ensure the original filename label (e.g. “XXVII_structure_1” is kept within the file name of the CIF you submit back to us.
We ask that they are excluded from the final ranking list, but please provide a supplementary document (word document or similar is fine) that specifies which structures resulted as equivalent. The label you keep within the submitted ranked list of structures is up to you, just as long as we can see which structure labels are equivalent in the information provided.
Since this has not been carried out by participants, please report a ‘.’ value in these cases.
Yes. If Free energies are given, the temperature at which the energies are calculated must be specified.
We will accept rankings based on 0K and higher temperatures. If Free energies are reported, we strongly encourage to report 0K lattice energies and rankings in addition to maximise the analysis we can carry out.
