SpecDB: A database for storing and managing mass spectrometry proteomics data

Data produced by mass spectrometer (MS) have been using in proteomics experiments to identify proteins or patterns in clinical samples that may be responsible of human diseases. Nevertheless, MS data are affected by errors and different preprocessing techniques have to be applied to manipulate and gathering information from data. Moreover, MS samples contain a huge amount of data requiring an efficient organization both to reduce access time to data, and to allow efficient knowledge extraction. We present the design and the implementation of a database for managing MS data, integrated in a software system for the loading, preprocessing, storing and managing of mass spectra data.
