To duplicate a sample record in the list of samples being submitted for microarray hybridization:

Start on the Sample View tab of the New Experiment Request module. This window is the part of the much longer step-by-step process of submitting a microarray hybridization request — see Submitting a Microarray Hybridization Request for a description of this process. This task will normally be performed as you reach the Sample View tab within this process.

Select the sample record whose settings you would like to duplicate in the new sample in the Samples list by clicking on the number next to its row. (You may actually click anywhere on the row, but that will also activate the field you click on for editing, so clicking on the number is safer.) The row of the selected sample will be highlighted in light blue.

Click on the Copy sample button above the list of samples. A duplicate of the selected sample will be added to the bottom of the grid.

Edit the data in this row for any variances between the new sample and the sample you copied by clicking on each column in that row where you would like edit data and then making whatever changes are appropriate in that field — see Editing a Sample from the List of Samples You Will Be Submitting for Microarray Hybridization.

Every field in the row will be duplicated from the original sample except for the cy3/cy5 label field (if applicable for the kind of hybridization you are requesting). In addition to making any other editing changes, you may need to select the appropriate label before proceeding further.
