To request the addition of lanes to a previously submitted sequencing request:

1. Start the Add Services wizard by clicking on either the Add services to Experiment Request button in the Experiments section of the home page of the application environment or the smaller Add Services to Request button along the top row of the application.

The Add services module will open with the Add services tab selected.

2. Select your lab group and the lab group member who submitted the original sequencing request.

3. Also select the appropriate category for the services you will be adding (the kind of sequencing request you are adding lanes to).

4. Select the previously submitted request from the list of existing requests that appears at the bottom of the window by clicking on it. These requests are organized by project under the current lab in the data tree.

5. Click on the Next button in the lower left corner of the window.

From this point on, you will be walked through a subset of the Illumina Submit Request tabs — see Submitting a Sequencing Request for a details of the complete original submission process that should resolve any questions that arise on these tabs. Then, on the Samples tab, you will be prompted to enter the additional number of lanes.
