Export a structure file

To export the selected portion of a currently-displayed structure (or entire structure, if nothing is selected), choose one of the following File > Export Data options:

• Export Structure – Available for documents with one structure. By default, the structure is exported in Protein Data Bank (.pdb) format. If desired, you may instead specify Macromolecular Crystallographic Information File (.cif) format. Make any other desired changes in the dialog, and then press Save to export the structure.

*Note: To be exported in Protein Data Bank (.pdb) format, a structure must contain ≤ 99,999 atoms and ≤ 62 chains. If you attempt to export a structure that exceeds these limits, you will receive an error message that the export failed. However, you can still export a portion of the structure that does not exceed the limits. For example, if a three-chained structure is too large to export, try selecting just one or two of the chains before re-attempting the export.

• Export All Structures – Available for documents with two or more structures. After selecting this option, a popup dialog opens:

Choose a file format from the dropdown menu (.pdb or .cif). Click Browse to navigate to the location where you wish to save the structure. When you have made the desired selections, press Export.

• Export All Selections – Available when a selection is made, and applies only to selected regions. By default, the structure is exported in Protein Data Bank (.pdb) format. If desired, you may instead specify Macromolecular Crystallographic Information File (.cif) format. Make any other desired changes in the dialog, and then press Save to export the structure.
