SyncPro : A synchronized visualization tool for differential analysis of proteomics data sets

In the comparative proteomics studies, visualization has become an emerging technique in the analysis. It provides an intuitive overview of large-scale mass spectrometry data sets with possibilities to further explore data details at different levels. While different visualization tools have already been developed, they are often designed to handle one or a few mass spectrometry data sets. Apparently, this is not enough as many proteomics studies involve many samples. It is much desired to simultaneously visualize all data sets in order to better examine data sets. In this paper, we present a visualization tool named SyncPro for differential analysis of multiple pre-processed proteomics data sets. It offers features to (i) compare many data sets simultaneously; (ii) facilitate data exploration through selection and extraction; (iii) quickly judge the quality of selected features. Our proposed method further enhances the functions of existing visualization tools.
