Thanks to the hard work and generosity of Igor power user Stephan Thürmer for these and many other improvements. Created a GUI for the AutoMPFit() function, allowing easier access to batch multipeak fitting.New baseline functions: ArcTan, Shirley, Tougaard.A Voigt peak with Gauss and Lorenzian FWHM instead of that annoying "shape factor".New versions of standard peak shapes with physically meaningful fit coefficients like Area.New peak shapes: DoniachSunjic, PCI (Post-Collision Interaction).(Prior to Igor Pro 9.00, to fit complex-valued functions to complex-valued data required writing a real-valued fit function that used a special organization of the data to pack real and imaginary parts into a single real-valued wave.) Multipeak Fitting Inferior sites (the outside concentric circle) are in orange.Ĭurve Fitting now supports fitting to complex functions. For example, the right frontal 3,4,8,57 sites (blue sub-branch) are highly correlated. The anterior sites (above the nasion) cluster together (red). The clustering analysis following PCA shows that adjacent sites are often clustered together. The 65 sites are distributed across the scalp. This example shows the hierarchical clustering of EEG electrode sites/channels. Output is a distance matrix if you start with a vector matrix, and/or a wave containing information needed to draw a hierarchical dendrogram. The input can be either a matrix in which rows represent vectors in a data space, or a square distance matrix giving the distance or dissimilarity between pairs of vectors. This example code shows the index of the trace's wave at the mouse position:ĭata Analysis Hierarchical Cluster AnalysisĪdded new HCluster operation that performs agglomerative hierarchical cluster analysis. Igor 9 adds tooltip hook functions so that an Igor programmer can provide a tooltip for any arbitrary rectangle in a window. Previously, all the boxes or violins in a single trace had to look alike. For instance, in a trace with several box plots, you can change the fill color of a single box. Graphics Box and Violin Plot per-dataset Propertiesīox Plots and Violin Plots now support per-dataset settings. This streamlines what used to be a process of selecting, cutting, changing the draw layer and pasting if you wanted to change the draw layer of a drawing object. Click the gear icon at the bottom of the window list and use the Display Text submenu to select Title.Īdded a Move to Layer item to the draw tools palette and to the draw objects contextual menu. The Window Browser and other dialogs that display lists of windows can now display titles of windows under or next to the window's icon instead of the name. It is also now possible to drag waves onto graphs and tables from the Waves in Window list of the Window Browser: Note that an expansion other than 1.0 may present an alternate GUI appearance in order to maintain functionality. New active areas allow you to append traces to specific axes and to make new free axes, as well as select a wave as an X wave.įor those times when a user-defined panel is just a bit too small to read easily or a bit too big to fit your laptop's screen, you can make that panel bigger or smaller using the new Panel→Expansion submenu or the ModifyPanel expand command.Īnd if every user-defined panel needs expansion or reduction, you can set that scale factor in the Miscellaneous Settings dialog to apply to them all, which is useful when working on small laptop screens. The ability to drag waves from the Data Browser onto a graph to make new traces has been enhanced. Igor's PDF export now supports transparency and does a better job of font embedding. You can also open and browse multiple HDF5 files and convert the data into Igor native formats. Igor also still fully supports the packed experiment format (.pxp) for backwards compatibility. You can set the frequency of saves and control whether autosave makes temporary backup copies of files or saves directly to open files.Įntire Igor experiments can now be saved using the open HDF5 file format, making your data immediately accessible to a wide array of programs that support HDF5. Prevent loss of work in the event of a crash or power loss by enabling Autosave from the Miscellaneous Settings dialog.

Some of these changes are highlighted below. Igor Pro® 9 contains hundreds of improvements, including 58 new operations and functions, and built-in support for HDF5.
