Changelog
Version 2.2.0 (2008/11/14) Major changes:
* Support for import of multiple files. New tab selection in the import wizard "Multiple image import", for merging multiple files into on project. * Multiple legends in the plot properties dialog. * The user can now change the order of classes inside legends by moving classes up or down in the class settings panel. The class settings panel is found in the data set table. NOTE: the sort option in the legend properties must be unchecked. * Added possibility to save models containing only the necessary data needed for an external prediction.
Minor changes: * Now possible to add more then one wild card for string selection in the selection panel, in data set tables. * Legends can show items by class from both color and shape. * Improved script functionality.
Version 2.1.0 (2008/10/06) Major changes:
* Missing values can now be replaced by median value of surrounding pixels during import. * A new modification, Prediction classes, added. Automatically created by the PLS-DA model. This enables automatic classification from the classes specified in the model. This can be used to color plots, create layers and/or select data points. More information can be found in the help shortly. * When creating a PCA model from classes, the models will be stored in a model container that can be saved as a single model. It will also be updated automatically if the data set is changed.
Minor changes:
* Tweaked MATLAB import and export. * Now possible to drag pixels from RGB plots to contribution plot settings. * Tweaked information shown in tooltips for some plots. * Improved X-axis descriptions for Spectral plots; this means that descriptions will now be fetched from the last data set interacted with instead of always from the original data. * Supports the SAC file format (Legacy and standard). * Optimized calculation speed of predictions and transformations. * Improved script functionality. * Updated 3D library to latest version.
Bugs fixed: * Colors should no longer reset in plots belonging to a different data set when changing the current data set. * Pasting of values during import should work better; rows would sometimes be transposed. * The user will get a warning while trying to create a PLS-DA model if here is no variance in the Y variables. Earlier this lead to an error message. * Fixed problems with moving classes to layers.
Known bugs: * Problems with 3D plots under Linux. * No support for 3D plots in 64bit Java under OSX. * Some problems under Windows Vista when computer is in a domain.
Version 2.0.21 (2008/08/07) Major changes:
* Interactions has been overhauled * Read support for SAC (SisuCHEMA Archive Container) file format.
Minor changes:
* Wild card search for variables has been added. * Logarithm transformation can now either update values or add new values (old default was new value). * Reverse colors for plots now possible.
Version 2.0.20 (2008/05/28) Major changes:
* MATLAB export greatly improved.
Minor changes:
* Help chapters updated to reflect changes made. * Enabled removal or renaming of identifier columns. NOTE: For changes to be reflected in the models, changes must be applied * Increased speed of copying plots to clipboard, especially for some plot types.
Version 2.0.19 (2008/05/14) Major changes:
* Plot legends have been improved. * Modifications in the data set are now shown in the order they are calculated. * Logarithms can now have constants (log(X + C)) * When creating classes, wildcards can now be used. * Wildcard selection for observations in the data set.
Minor changes:
* Screen shots shown in preview for new saved projects. * Excel import times improved when using file with several sheets. * Script improvements.
Version 2.0.18 (2008/04/22) Major changes:
* New functionality for manually adding Y variables by setting a selection to a specific value. * Improved image import where a preview of the image is shown. It is possible to exclude both pixels and wavelengths in the image preview. * Added functionality for correcting images with a set of standard images. Spectral unit conversion to reflectance and pseudo-absorbance is possible. * Support for reading .HIPS file format. * Support for writing MATLAB files (.mat) and ENVI files.
Minor changes:
* Observed vs Calculated plot for PLS models is easier to use. * Observations/variables from a test set is greyed out when excluded. * Added warning when it is likely too many subclasses would be created from some actions (would be very slow). * New (not loaded) Spectral plots from original data will have a set maximum value (based on maximum in the data) . * Model collections have been tweaked to display more useful plots. * All functionality in the data set menu for observations are always available in order to avoid confusion.
Version 2.0.17 (2008/03/04) Major changes:
* Added support for 3D hardware acceleration for Contour 3D plots. NOTE: 3D acceleration can be turned off in Tools/Options/Global 3D Settings. * Add/remove component functionality in model overview plot * Logarithm transformation is fixed when missing values are present * Added support for creating spectral angle maps from image data * Data range for Contour2D, Contour3D and RGB image plots is now updated when new component is added or removed * The viewing of identifiers is improved. * Fixed error for RGB image plots when certain observations are excluded.
