+# MOF solvent removal
+
+## Summary
+
+Scripts included in the supporting information of the article "Development of a Cambridge Structural Database Subset:
+A Collection of Metal–Organic Frameworks for Past, Present, and Future", Peyman Z. Moghadam, Aurelia Li,
+Seth B. Wiggin, Andi Tao, Andrew G. P. Maloney, Peter A. Wood, Suzanna C. Ward, and David Fairen-Jimenez
+*Chem. Mater.* **2017**, 29, 7, 2618–2625, DOI: <https://doi.org/10.1021/acs.chemmater.7b00441>
+
+Scripts are essentially equivalent: one is designed to be run through the Mercury CSD Python API menu to
+remove solvent from a single structure present in the visualiser, the second runs from the command line
+and takes a list of CSD entries (a .gcd file) to run through the solvent removal process in bulk.
+
+## Requirements
+
+Tested with CSD Python API 3.9.18
+
+## Licensing Requirements
+
+CSD-Core
+
+## Instructions on running
+
+For the script Mercury_MOF_solvent_removal.py:
+
+- In Mercury, pick **CSD Python API** in the top-level menu, then **Options…** in the resulting pull-down menu.
+- The Mercury Scripting Configuration control window will be displayed; from the  *Additional Mercury Script Locations*
+section, use the **Add Location** button to navigate to a folder location containing the script
+- It will then be possible to run the script directly from the CSD Python API menu, with the script running on the structure
+shown in the visualiser
+
+For the script Command_prompt_MOF_solvent_removal.py
+
+```cmd
+python Command_prompt_MOF_solvent_removal.py <search_results>.gcd
+```
+
+```cmd
+positional arguments:
+  input_file        CSD .gcd file from which to read MOF structures
+
+optional arguments:
+  -h, --help            show this help message and exit
+  -o OUTPUT_DIRECTORY, --output-directory OUTPUT_DIRECTORY
+                         Directory into which to write stripped structures
+  -m, --monodentate
+                        Whether or not to strip all unidenate (or monodentate) ligands from the structure
+  -s SOLVENT_FILE, --solvent-file SOLVENT_FILE
+                        The location of a solvent file
+```
