Graphical user interface overview. The user interface provides multiple ways to access information stored in the database. The experiment preview section shows previews of experiments associated with an image in the database. These previews are linked to details which include more elaborate descriptions of the experiments, and, if available, a clickable image map for each experiment with indication whether confident protein identification has been achieved for that area. A list of all measured spots is available, regardless of whether an image is provided. Hot spots or list of spots lead to the detailed protein, peptide, and MS information stored in the database. This section shows confident protein identifications at the top, with all other peptide identifications listed below. All areas can be reached via the search facility provided in the user interface. A summary of information regarding the confidently identified proteins can be exported as a text file with comma-separated values, which can be imported by most spreadsheet applications.
