The Plate Library
The Plate Library is a visual collection of the different plate types which are recognised by Antha and can be used when selecting specific types of input and output plates in the Workflow Editor.
About this tutorial
In this tutorial, you will be shown an example plate with its diagrams in order to learn how to read the information from the library and you will be guided through a worked example of using the Plate Library.
Things you'll need
Before you get started you will need an Antha license so that you have access to Antha OS.

The Features of the Plate Library
Basic Plate Information
Basic information can be found in the top part of each plate card.
The name for each plate is meant to be descriptive of the plate's function and may not perfectly match the vendor-given name.
The logo of the vendor for each plate is shown in a circle in the top left hand part of each plate card.
Descriptive Additional Information
Certain types of plates have an additional line of information, such as amount of agar which is pre-poured into the plate, whether the plate is skirted or not, or other information which is important but not listed elsewhere.
The Plate Diagrams
Key visual information about each plate can be found in the middle section of the plate card.
The left side of the diagrams will show a top-down view of each plate. These view are similar to those found in the Plate Prep step of the Job timeline.
Wells of a plate come in many different styles, such as flat-bottom, round-bottom, v-bottom, and conical. The profile view of the plate card will show you what shape each well is and whether the plate is skirted or not.
The first number, in green, represents the maximum volume which each well of the plate can hold. The second number, in red, is the residual well volume, i.e. the amount of liquid assumed to be left behind in the well even if everything is pipetted out of it. The residual well volume is always added to nominal well volumes when using plates in order to ensure that there is a sufficient but economical amount of liquid when running a job.
Additional Plate Information
Less important but still useful information about the plates can be found at the bottom of the Plate Card.
Antha uses unique code names to represent each plate type. When you select a special input or output plate in the Workflow Editor, this is the name which will appear.
Some plates require an accessory, such as a cooler block or rack. If one is needed, this is where it will be listed.
The catalog number is the vendor-specific identifier of the plate. Where possible, this entry is also a link to the vendor's website.
Some plates are used only in special cases, such as with electrophoresis or cooling. Where applicable, this special case is listed here.
Searching the Plate Library
Searching for a specific plate in the Plate Library is easy. Simply type a search term in the search bar and the list of plates will be automatically filtered for you.
Using the Plate Library
The Plate Library is a handy tool for specifying input or output plate types in the configuration section of the Workflow Editor
Specifying Input Plate Types
One of the things you may want to specify is a global input plate type. To specify the input plate type globally for all of your elements in your workflow, click the "add new item" button under "inputPlateTypes"
From here click on the blue button with the white magnifying glass to search for a plate type from the Plate Library.
A window with the different available plates will appear. Each Plate Card contains key information about each plate available to you.
To aid in the search for the right plate, you can filter your results with keywords in the search area.
Once you find the plates you're looking for, click on the card to activate it. Only one card can be selected at once. Click "Accept" to continue.
Your newly selected plate is now visible.
To add a riser or other type of carrier to this plate type, click on the dropdown menu for carriers.
Choose the carrier you wish to add to this plate type and it will be added automatically.
Repeat this process to add additional plate types, if needed.
Once a new plate type and riser has been selected you will notice that the information in the Preferences window will have been updated to reflect that an Input Plate Type has been selected.
Specifying Output plate types
The Output Plate Types option works in the same way as the Input Plate Types option in that it globally sets the output plate type for all the elements in the workflow.
However, If an element has a parameter option to set an output plate type then this will trump the Output Plate Type selected in the Configuration side bar.
