These topics describe the Proteome Discoverer Daemon utility, which you can use to perform a search either locally or remotely by using its application window, the command line, or a parameter file that contains command-line commands. You can use it to start workflows, monitor job execution on the configured server, perform batch processing, and process Multidimensional Protein Identification Technology (MudPIT) samples. The Daemon utility can perform multiple searches on multiple raw data files taken from multiple samples or from one sample.
