4. Go to ACQUITY Sampler > Plate Generator.

ADDITIONAL INFORMATION

Alternatively, the user can copy the Plates and Racks folders located in the C:\MasslynxBackup folder and paste them in the current C:\Masslynx selecting YES to the questions regarding overwriting the existing files.

Note: The Plates and Racks folders hold the files that define the bed layout and the plate definitions. Replacing the new Plates and Racks folder in the current Masslynx folder with those from the MasslynxBackup folder will reset the plate definitions and bed layout to the setting from before software was reloaded or upgraded.
