Data Browser: Samples

The Sample Browser allows users to create and manage samples they are authorized to access. Access permissions are granted through lab-based, user-based, or collaborative permissions authorized by a Principal Investigator (PI).

The Sample Browser includes:

• Create New Sample button that allows creating one or multiple samples
• A Navigation Pane on the left side for switching between sample views and hierarchical organization of My & Lab data described below.
• A Sample Table for displaying rows of samples with columns representing metadata that may be sorted and filtered.
• Customization Tools in the upper-right corner to configure columns, saved views, and filters.
• Advanced Selection, Sorting, and Filtering of samples
• Ability to perform Actions quickly and easily from a context menu to one or more samples

Navigation Pane

The Navigation Pane allows users to quickly access datasets across different categories.

All Samples

Displays all samples the user can access.

My & Lab Data

Displays samples accessible via user- or lab-based permissions.

This section includes an organization mirroring a file system:

• My Collections – personal collections created by the user.
• Spawned Sample Collections - collections created by the user through multi-sample creating tool.
• Projects – high-level groupings for sample organization that mirror data organization in Datasets Browser and consists of
  • Studies – reside inside Projects
    • Collections – reside inside Studies

Sample Table

The Sample Table displays all samples for which the user has at least read access.

Table Rows

Each row highlights a sample in the NAN archive

Table Columns

Columns represent different metadata fields for the sample. There is a default list of columns that are displayed, but users can toggle different columns on and off as desired by selecting the wrench icon in the upper right hand corner of the dataset browser. Columns may be re-ordered by dragging them. The columns to be displayed, along with their order, is saved in the NAN database as a user preference and will persist across sessions, browsers, and computers. See Sample Columns for complete list of columns with a short description and the types of filters that may be applied.

Icon badges

Icon badges in the Name column represent additional information about the sample and provide navigation links as described here

• A small clock icon indicates that the dataset associated with the sample has been published. Clicking the icon will allow you to navigate to previous published versions or the datasets and associated samples
• A link icon indicates that the sample has been linked to a dataset and clicking the link icon will bring you to the Dataset Browser filtered on the linked sample.

Pagination

At the bottom of the table is a pagination control. Users can move between pages and adjust the number of rows displayed per page: 25, 50, 100, or 500 samples per page
