An FDR metric for top-down proteomics.

abstract：:The importance of locating proteins in their context within cells has been heightened recently by the accomplishments in molecular structure and systems biology. Although light microscopy (LM) has been extensively used for mapping protein localization, many studies require the additional resolution of the electron mic...
