The ODIN user interface is an easy-to-use program to edit, compile, test, and simulate NMR sequences interactively in a single window. Thereby the NMR sequence is compiled as a plug-in (shared object on UNIX or DLL on Windows) and linked into the user interface. After that, the sequence can be analyzed in various ways (vizualisation, simulation). This documentation will describe all elements of the user interface and their functionality to accomplish this task.
A typical session with the ODIN user interface involves the following steps
After successfully compiling and linking a sequence, the central part will contain a grid of widgets which contain the sequence parameters. Each time a parameter is changed, the sequence will be recalculated.
The lower part contains a text field which displays warning/error messages from the current sequence, compiler errors, etc.
At the very bottom, the current status of the user interface is indicated by a green/red light and a short message. For example, if compilation of the sequence fails, this will be indicated in the Status Bar.
Creates a new sequence by taking the source code of another sequences as a template
Opens the source code of a previously used sequence
Closes the current sequence
Saves the current state of the ODIN user interface (compiler settings, debug levels, sequence parameters, system configuration, ...)
Saves the current measurement protocol in a single protocol file
Loads the current measurement protocol from a single protocol file
Exit the ODIN user interface
All entries in this menu can also be found in the tool bar with the corresponding icon.
Opens an editor (customizable via Preferences->Settings) to edit the source code of the sequence
Compiles the current sequence, and if successful, links it into the ODIN user interface
Opens a dialog to edit the current geometry, i.e. slice positioning
Plots the sequence using an embedded plotting window
Shows the k-Space during acquisition
Simulates the current sequence. First, a dialog will pop-up to ask you for various simulation settings. Then, after loading a virtual sample, a virtual NMR signal will be created which can then be viewed in the plotting window. The simulated raw data together with the parameter files is stored under $HOME/odin-methods/<current-method>/sim. After simulation, the reconstruction is started using the simulated raw data.
Shows the description of the sequence together with some additional information
Displays the sequence tree, i.e. the internal layout of the sequence
Displays all parameters used for automatic reconstruction
Displays a list of used SeqPulsar pulses in the current sequence. By clicking an item in the list, the Pulsar user interface will pop up to show the parameters of the pulse.
Edit the Settings of the ODIN user interface
Edit the system configuration
Load the system configuration from a file
Change the debugging/tracing settings. This option is not available if ODIN was compiled as a release
