User guest can be defined to login automatically with basic access to unrestricted studies.
The Browse Tab is the usual first page (landing page) displayed.
This page holds metadata about known studies, organised under "Programs".
Studies can have associated Assays, Analyses, Folders and Files.
Studies are linked by STUDY_ID to studies loaded in the Analyze tab.
Various searches are available in the text box. The pull-down list defines the search category, listed in alphabetical order. The categories are defined in the searchapp.search_keywords table use dto generate the list in the UI automatically.

If loaded, Private Studies may be restricted to Admin users. The usual example if the Cell-Line Use Case from the TraIT project.

Builds queries in one or two subsets to explore a cohort or to compare two cohorts.
Any node from the Navigate Terms tree can be dragged to either subset.
A query must have at least one "Include" criterion to identify the study of interest.
A single string leaf node (e.g. Demographics: Female) will select those individuals with the term defined
Additional strings can be dragged to the same subquery to select any of the values as matching.
A folder node will include all individuals with that node defined
Numeric nodes will offer a choice of value ranges or all nodes with a value defined.
High-dimensional nodes will offer all nodes with a value defined or allow a search for a single gene and a range of expression values.
A default set of i2b2 values is displayed: Age, Sex/Gender, Race.
Any other nodes used in the query definition will also be displayed.
Furher nodes can be dragged into the summary statistics panel, including high-dinmensional nodes.
A default set of i2b2 values is displayed: Age, Sex/Gender, Race plus patient ID, sample ID, subset
Additional nodes can be dragged from the Navigate Terms tree.
Column headings are kept unique. If two columns have the same last-level value in their paths fiurther levels are added until the displayed column name is unique.
