Menu Bar
========
The menu bar at the top of the *SasView* window gives you access to additional features of the program:

File
----
The File option allows you load data into *SasView* for analysis, or to save the work you have been doing.

Data can be loaded one file at a time, or by selecting multiple files, or by loading an entire folder of 
files (in which case *SasView* will attempt to make an intelligent guess as to what to load based on the 
file formats it recognises in the folder!). Data can also be loaded by dragging and dropping files directly
onto Data Explorer.

A *SasView* session can also be saved and reloaded as an 'Analysis' (an individual model fit or invariant 
calculation, etc), or as a 'Project' (everything you have done since starting your *SasView* session).

Edit
----
The Edit option allows you to:

- undo/redo your recent changes;
- copy and paste parameters between *SasView* analysis windows;
- copy parameters from a *SasView* analysis window to the Clipboard as either tab-delimited text (compatible with Microsoft Excel) or LaTex-wrapped text;
- generate a summary 'Report' of the most recent analysis performed;
- reset parameter values in the P(r) Inversion analysis page.

View
----
The View option allows you to:

- show the Batch Fitting Results Panel if it has been closed;
- show/hide the Toolbar of icons below the Menu Bar;
- select the default location that *SasView* looks in for data to analyse (the *SasView* installation directory, the initial default, or a custom folder). NB: any change only takes effect when *SasView* is restarted;
- change the default assignment of categories (*Shapes*\, *Shape-independent*\, *Structure Factor*\) for fitting model functions.

Tools
-----
The Tools option provides access to a comprehensive range of tools and utilities. See :ref:`tools` for more information.

Window
------
The Window option allows you to select which *SasView* windows are visible.  

Analysis
--------
The Analysis option provides access to the key functionality of *SasView*:

- Model Fitting;
- P(r) Inversion;
- Invariant Analysis;
- Correlation Function Analysis (*SasView* 4.1 and later)

See :ref:`analysis` for more information.

Fitting
-------
The Fitting option allows you to:

- create a new FitPage;
- setting up a Constrained or Simultaneous Fit;
- change optimiser (under Fit Options);
- view fit parameter correlations, distributions, and convergence traces (under Fit Results);
- create a Plugin Model.
- edit a Plugin Model.
- manage Plugin Models
- create a Sum/Multiple Plugin Model
 

Help
----
The Help option provides access to:

- this help documentation;
- a :ref:`tutorial` on using *SasView* (in pdf format);
- information on how to acknowledge *SasView* in publications;
- information about the version of *SasView* you are using;
- the :ref:`marketplace`\ ;
- a check to see if there is a more recent version of *SasView*.
