Once you find an experiment hit, you can virtually harvest your crystals and assign them to a Synchrotron Trip.
Open an experiment with crystals.
Then, go to the Drop(s) tab in the Images tab set.
Double-click on a well that contains the crystal you want to harvest in Canvas view, to open that well in Drop view.
Click the Harvest Crystal button and draw a rectangle around the crystal location within the drop.
Once you have drawn a box around the crystal, the Crystal Definition window will appear. Here, you will need to define the following:
Note: You can see the drop from the Image Preview on the right side of the Crystal Definition panel.
Note: You can change the format of the default crystal name in ROCK MAKER Global Preferences. For more information, read System Properties.
Well & Drop. Shows which well and drop you harvested the crystal from.
Protein Name. Shows the name of the protein that the crystal is made of.
Synchrotron Trip. The Synchrotron Trip definition will be updated automatically after you have selected a Dewar for your harvested crystal.
Dewar. Select the Dewar where the crystal is located from the dropdown list.
Pucks. Select the Puck where the crystal is located from the dropdown list.
Position. ROCK MAKER will automatically assign the pin position for your crystal in the selected puck. For better visualization, you can also see and select another position by clicking the Position button next to the Position field. Available pins are shown in green and red indicates that a pin already contains a crystal. Orange is the current pin selection for your crystal position. After you have finished, click .

Note: Data Collected can only be selected if the Data Collection Date is in the past.
Note: Structure can only be selected if the Data Collection Date is in the past.
Resolution. Type the resolution at which the structure was finally refined.
In the Cryoprotectant panel, define the cryoprotectant you used prior to freezing your crystal:
Note: You are required to fill in the cryoprotectant information.
- Click the + button to manually add the cryoprotectant by defining these fields:
- Ingredient. Required field. Type the name of the ingredient that you are going to use.
- Conc. Required field. Type the concentration of the ingredient that you are going to use.
- Conc. Unit. Required field. Select the concentration unit of the ingredient that you are going to use.
- pH. Required field. Type the pH of the ingredient that you are going to use.
- Protocol. Enter any relevant details about how the crystal was frozen.
Note: If you want to save your current cryoprotectant selections for future use, type a descriptive name for your cryoprotectants in the Save Cryoprotectant as box. Your selections will be saved when you click Apply after you are finished inputting your data in the Crystal Definition window.
In the Soaking panel, you will define the name of any compound (or ligand) that you soaked your crystal in, as follows:
- Click the + button to add a new soaking compound, and then define the following fields:
- Name. Type the name of the compound used.
- Conc. Type the concentration of the compound.
- Conc. Unit. Select the concentration unit of the compound.
- Time. Type the duration of time for which the crystals were soaked.
- Text Info. Add any additional information relevant to the soaking process.
Browse a document from a directory and attach it in the Attachment box of this crystal record, if desired.
Type any additional information regarding the crystal in the Notes field, if desired.
When you are finished defining your crystal, click Apply to mark the crystal as harvested. A harvested crystal icon will appear on the experiment plate icon.
Note: Harvested crystals that do not have their synchrotron trip, puck, and dewar defined can be found by opening the project the crystal came from. Crystals with their synchrotron trip, puck, and dewar already defined can be found in the relevant Synchrotron Trip in the Crystal Tracking node on the Explorer.
