- From the CSSI Data Portal home page, click the Browse button or select Investigations > Browse.
The Browse Investigations page appears, showing pie charts at the top and a list of investigations below them. All investigations currently included in this release of the CSSI DCC Portal appear in the list. A subset of the page appears in the following screenshot.

- 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 at the top. These pie charts represent three of the fields, Study Protocol Name, Study Assay Technology Type, and Study Assay Measurement Type, that occur in the metadata of the 8 investigations currently in the portal (as of January 2017). The values for those fields, as well as a count for each value, appear in the pie charts. The count represents the number of times that field value occurs in all of the investigations currently in the portal.
For example, in the default pie charts represented in the above screenshot, the Study Assay Measurement Type pie chart shows that one 1 investigation used genome sequencing, six 6 used imaging assay, and two 2 used transcription profiling. Note that there are 9 field values and only 8 investigations because 1 investigation listed 2 values for Study Assay Measurement Type. You can determine which investigation that was by clicking on each pie slice and reviewing the details in the list below.
Click one or more field values in the pie charts ("slices") to filter the data by that/those field value(s). The more field values 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.
In the following screenshot, a user has selected at least one field value in each pie chart. The selected values are sample collection and summarize trimmed reads in the Study Protocol Name chart, nucleotide sequencing in the Study Assay Technology Type chart, and genome sequencing in the Study Assay Measurement Type chart. Only one investigation matches all of these selections and appears in the list below. To reduce the amount of filtering, you can click Reset All to return to the default pie charts, or reset on an individual pie chart. You can also return to the default view by selecting Investigations > Browse. A list of investigation details below the pie charts. The investigation list shows details associated with the investigations that match your pie chart selections. For example, in the following screenshot, a user has selected one field value in 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.
four
The list below the pie charts match the pie chart selections. The list includes only those4 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.
Info If you have added or removed fields from the pie charts, the new or removed fields are also reflected in the Investigation list fields.

- From the CSSI Data Portal home page, click the Search button select Investigations > Search.
The Search Investigations page appears. - In the search box, enter a keyword or phrase. Keywords are any word that appears in the fields belonging to any investigation, study, or assay in the CSSI DCC Portal. This includes all file columns, field definitions, and placeholders that describe the structure of the data collected in this study.
Search results appear immediately, using the context currently in the Search for box, which by default is Investigations. The time the CSSI DCC Portal took to first search for the keyword or phrase and then render the results on the page also appear. - In the Search for box, change the context for your search if desired. Select Investigations, Studies, or Assays. Examples of each search result follow.
In the following example, the keyword is "genomic" and the context is Investigations. Three investigations appear in the search results, along with information about each one that includes the investigation name, number of studies, number of assays, number of files, and description.
In the following example, the keyword is "genomic" and the context is Studies. Three studies appear in the search results, along with information about each one that includes the study name, name of the investigation the study is associated with, number of assays, number of files, and description. In these cases, the investigation name and study names are identical.
In the following example, the keyword is "genomic" and the context is Assays. Three assays appear in the search results, along with information about each one that includes the assay filename, name of the study that the assay is associated with, name of the investigation the assay is associated with, number of files (such as image files), and description. - Click any investigation name, study name, or assay filename to explore the data further.
