Start by exploring the data by click on ''Browse data'' in the main menu. This will take you to a screen with four tabs, which are explained in more detail below.

=== Overview ===

* The first tab named ''Overview'' will present you with a summary view of all entries in this investigation.
* You can change investigations with the arrowed buttons at the top.
* Clicking on a type of data will take you there. This is a shorthand: you can always browse to all datatypes using the tabs ''View data'', ''View annotations'', and ''View files''.
* Similarly, the ''Add'' button is a shorthand to be taken to the tabs of this data category (data, annotations or file) where you can start adding data with the ''Add new record'' button.
* The default view will display 4 entries for each type: use ''Show all'' to expand.

there also a short hand 

=== View data ===

* This tab allows you to add, view and remove data matrices. These are rectangular pieces of (raw) experimental data accompanied by row- and column names.
* Matrices themselves are annoted with the 'Data' entries, while their row- and column entries are annotated as separate (strong) datatypes found in the ''View annotations'' tab.
* There are a number of plugins that will help you deal with matrices:
 * Manager = Uploads data and views the numerical/textual data.
 * Heatmap = View numerical values as a customizable heatmap.
 * Rplot = Create graphical plots using R.
 * Inspector = Check whether annotations are missing.
 * Delete storage = Delete source data linked to this Data entry.
 * !ManagerDev = Advanced manager - currently under development!

=== View annotations ===

* This section allows you to add, view and remove annotations such as ''Individual'', ''Gene'' or ''Marker''.
* These annotations are often linked to a data matrix, but they don't have to be.
* You can view display a list of records which is manipulatable using the ''View'' menu, search box, or paging buttons.
* When clicking ''edit record'' you can change the values of a record.
* Click ''More annotions'' to see more exotic data types such as ''!DerivedTrait'' or ''!EnvironmentalFactor''.

=== View files ===

* Here you can add files.
* Specify the name and extension of the file in a standard record.
* Now upload its contents.
* A viewer will serve out the contents based on the extension.
