• • Pie charts that show fields from the investigations. When you first open the page or reset it to clear all selections, three pie charts appear that show counts from the eight PSON investigations that match the values for Study Protocol Name, Study Assay Technology Type, and Study Assay Measurement Type. For example, in the screenshot above, the Study Assay Measurement Type pie chart shows that one investigation used genome sequencing, six used imaging assay, and two used transcription profiling. There are nine field values and only eight investigations because one investigation used two types of Study Assay Measurement Type.
    
    Click one or more pie slices to filter the data by that/those field value(s). The more slices you select, in one or more pie charts, the more narrowly you filter the investigation data and the fewer investigations match your selections. The investigation list refreshes each time you filter the data in this way. You can also customize which fields appear in the pie charts and how many pie charts appear by adding and removing fields. You can return to the default pie charts anytime by clicking either Reset All or selecting Investigations > Browse.
    
    
  • A list of investigation details below the pie charts. The list shows details associated with the investigations that match your pie chart selections. For example, in the following screenshot, a user has selected one slice of the Study Protocol Name pie chart: plate cells. The number 4 next to the label plate cells means that four investigations are associated with the Study Protocol Name field value of plate cells. Those four have a null value for Study Assay Technology Type, which is the second pie chart, and all use the same Study Assay Measurement Type of imaging assay.
    
    The list below the pie charts match the pie chart selections. The list includes only those four investigations that have a Study Protocol Name field value of plate cells. Details for each investigation in the list includes the same fields represented by the pie charts: Study Protocol Name, Study Assay Technology Type, and Study Assay Measurement Type, plus the study name and description. The list also shows additional data about each investigation, such as the other keywords used in the Study Protocol Name field. You can return to the default (full) list at anytime by selecting Investigations > Browse.

     By filtering the investigations in the portal so that only those matching the fields you select appear in the pie charts and the list. If you do not filter the investigations, you see a pie chart analysis of the three default filters: Study Protocol Name, Study Assay Measurement Type, and Study Assay Technology Type. All of the investigations appear in the list.
     InfoNote that not all investigations in the portal have a value for each field. For example, in the Characterization of Circulating Tumor Cells (CTCs) study in the screenshot above, there is no value for Study Assay Technology Type. This is reflected in second pie chart for Study Assay Technology Type at the top of the screen. In that pie chart, five  investigations have no value for this field while the remaining three have the value of "nucleotide sequencing."
