Sample Explorer

Sample Explorer lets you search for tissue and blood samples of interest so that you can learn more about the samples.

The Sample Explorer window has two panes:

Right pane

Lets you initiate a search for samples using one or more pre-defined filters. For information, see Select a Primary Search Filter, next.

After you initiate a search, the pre-defined filters are replaced by search results. For information, see View and Refine Sample Search Results.

Left pane
Reflects the currently selected filters and the number of a filter’s samples that appear in the search results.

Select a Primary Search Filter

This pane of the Sample Explorer window lets you initiate a search for samples by selecting the primary search filter. The primary search filters appear when you first open Sample Explorer, or, after you have begun a search, when you click Clear Search in the upper-left corner of the pane.

Click a filter to initiate a sample search.


Note that the number of samples that are associated with a filter appear in parentheses after the filter name.

View and Refine Sample Search Results

After you select a Select a Primary Search Filter:

  • The right pane displays the search results.
  • The left pane contains all selected and de-selected search filters, allowing you to narrow the search results.

The following figure illustrates the sections of the Sample Explorer after a primary search filter has been selected:


Tasks you can perform in the Sample Explorer window include:

Select and Remove Search Filters

You can refine a sample search result by adding and removing search filters, including the primary filter you initially selected. Search filters are listed in the left pane of the Sample Explorer window.

To select or remove a search filter, check or clear the check box next to the filter name.


Clicking a filter name rather than the check box next to the name will select that filter and deselect all currently selected filters.

The filters you select are joined together in a search string by the logical operators AND and OR, as follows:

  • Filters within a filter category (such as DataType) are joined by OR.

  • Filters in different filter categories are joined by AND.

    For example, the search string for the filter selections illustrated below is:

    (RBM OR Gene Expression) AND (Colorectal Cancer OR Gastric Cancer)
