When you open the Plate Prep task view, you are presented with your first auto-generated plate. If there are any input plates added by the system, they will show up first in blue. In this particular example, there are not yet any input plates because we need to upload a plate layout file. To do this, click the blue "edit plates" button.

You will be prompted to confirm that you want to re-simulate your workflow. This step is important to make sure that the plate you've uploaded is valid and will work with the other components in your custom workflow. Click "Confirm" to continue.

If your job re-simulates successfully, you will be brought back to the plate view where you will see your newly uploaded plate. Once you are satisfied with all of your plates click "Confirm Plate Prep" again.

A dialog will appear asking you to name and barcode your plate if you haven't done so already. Click the blue text which reads "click here" to name and barcode your plate.

How to Physically Prepare an Input Plate Based on the Instructions Given by the Plate Prep Task View

The most useful part of the Plate Prep view is using it as a guide for physically preparing the input plates you'll need for your your job. With the visual cues offered by the Plate Prep view, making up your plate is fast and simple.

Knowing the Contents of a Well

To find out what the contents of your input plate are supposed to be, you can click on individual wells, a single row, or a single column to highlight its contents. By doing so, the volume will appear in the selected well and the content details will be highlighted.

Here is what it looks like when a well is highlighted...

Colour Guide

The contents of a plate are colour-coded based on how the liquids are handled by the liquid handling robot.

How to Download a Plate

There are three places where you can download the plate layout file: The Type IIS Construct Assembly Protocol card, the Workflow Information Sidebar (which is shared between the Job Queue and the Dashboard) or within the Plate Prep task of an existing job.

Getting the Template Files Through the Type IIS Construct Assembly Protocol Card

The templates for all of the files compatible with the Antha OS environment, including the plate prep layout, can be found in the Type IIS Construct Assembly Protocol card.

To access the Type IIS Construct Assembly Protocol card, select the "Protocol" tab at the top of the app and click the "get started" button in the "Type IIS Construct Assembly" card.

Uploading files

Within the protocol card there is a link for downloading a .zip of template files. Click on the yellow text reading "Download the template files" to download this .zip archive.

Uploading files

Once the file has downloaded, unzip the archive to access the files.

Uploading files

Within the unzipped folder you will find three template files: A sample .json bundle file, a sample .gdx design file, and a sample .csv plate file.

Uploading files

Open the .csv plate file to begin editing.

Getting an Existing Plate Layout File from the Dashboard or the Job Queue

You can modify the input plate in the Dashboard or the Job Queue by downloading the auto-generated input plate, editing it, and re-uploading it.

Scroll down on the Workflow Details sidebar until you see "Plate files." Click on the input plate (the one with the blue icon).

Uploading files

Open the downloaded file and save to a memorable location

Getting the Template File in the Plate Prep Task of your Workflow

You can also modify the input plate in the Plate Prep Task View by downloading the auto-generated input plate, editing it, and re-uploading it.

From the Dashboard of a selected Job, click on the Plate Prep task.

Uploading files

Choose a plate for which you would like to download the plate layout file. Click the word "Download" above the plate image.

How to Find Plates in the Inventory

If you would prefer to load a plate which already exists in your inventory, you can do so by searching for it by its barcode in the inventory. To do this, click the blue "edit plates" button and select "Upload plates from file or inventory." Then simply select the "Search by barcode" area and enter the barcode of the plate you wish to import.
