Figure 4From: 2DDB – a bioinformatics solution for analysis of quantitative proteomics dataVisualization of data. Visualization of data. All these plots are from the experiment discussed in the text. This Figure illustrates four simple graphs designed to give a quick overview of the data, a) is a scatter plot of the theoretical molecular weight of each identified protein over a certain prophet probability (user-settable) against the scan number. The scan number is the sequential number online MS assigns to each spectra it acquires, and since these spectra are acquired with a given time interval, the scan number can be utilized as a pseudo retention time, b) is a histogram of proteins that are significantly regulated (p < 0.05), and a ProteinProphet probability over 0.6. c) is a mass spectra from one of the peptides used to identify HSP72_HUMAN heat shock-related 70 kDA protein 2. These graphs are generated on the fly and enables the user to assess the quality of the dataset.Back to article page
