What is the benefit of using the Sample Management System in Array Studio?
From Array Suite Wiki
Sample management makes it very easy to integrate with internal LIMS or sample systems.
The advantage is that it allows a user to easily identify and associate samples with raw data files.
Additionally, it automatically attaches sample annotations (designs) when the user imports the data.
Finally, it can be used to run pipelines. You can right-click on a sample set, choose a pipeline to run, and it will automatically create the project for you (no need to re-enter the meta data for the project) based on the sample set used. This is extremely convenient if you are always running the same type of initial analysis.
