CrystalDiffract may be configured to ignore relexions below a minimum d-spacing and/or above a maximum number of reflexions. These settings may be edited, and are there to ensure that the program remains usable, even when very-large structures (e.g., proteins) are being used.

To override CrystalDiffract's default settings, please follow these steps:

1. Use the Preferences command to display the Preferences dialog.

2. When the dialog appears, click the Profile tab to select it.

3. Locate the Generate Reflexions group, and uncheck the Limit number to checkbox (or enter a larger number of reflexions here). You may also want to adjust the minimum d-spacing setting.

4. Click the dialog's Save button to record these settings as your new, default ones.

5. The new settings will apply to any new windows that you open in the program. Existing windows will remain unchanged.
