freeQuant: A Mass Spectrometry Label-Free Quantification Software Tool for Complex Proteome Analysis

Figure 1

The Interface of freeQuant. Four modules were involved in freeQuant. First, protein information contains basic information of the current protein, such as protein name, relative abundance, and functional annotations. Second, spectral abundance atlas shows the distribution and relative abundance of identified peptides. Third, sequence shows the protein length, molecular weight, and protein coverage. Fourth, distinct peptide shows the correlative information of identified peptides.
