Release Notes Version 7 5 1

Changes and Bug Fixes in Version 7.5.1

File	Comment
analysis	Fix for LV's not getting updated after crossterm Make sure preprocessing is a ROW vector before adding clutter (avoids indexing error when loading manually-created preprocessing) Fix bug where filternwayprepro option wasn't being saved Add 'whittaker' 'baseline' to methods that are allowed with Multiway data (although they ONLY work on mode 2 of the data) Add exception to allow ncomp > max size data for ANN analyses (because it is # of nodes which is allowed to be > # of inputs) Fix for autorebuild function not existing when options are changed in SIMCA Add "reduced stats" to analysis to make it easier to access reduced statistics in scores plot and make "both" option the default Enable cross-validation for ANN Add GUI-based tests for multivariate Y for methods that can't handle it (when found, send user directly to "select y column" interface) Allow 0 for 2nd layer nodes in ANN settings (meaning do not use a second layer - bug in 7.5 ALWAYS used two layers) Fix for bug in # of components validation in ANN settings (was updating the wrong edit box) Fix for misassigned compression components options field Show PARAFC constraints option at "novice" level of options Fix fontsize on panels to be more reasonable Add help button to mcr constraints gui Include constraints in the items shown with PARAFAC model information Fix for copying figures on MAC Fixed a semi-severe bug in PARAFAC split half analysis which the percentage goodness was in error (The plots though were all good)
ann	Add new back-propogation algorithm (faster and more accurate.) Enable cross-validation with full support for all leave-out methods. Add I/O version where number of nodes in one or both layers can be entered as an argument
autoimport	Fix for possible explode-into-workspace problem if object is a cell When XLS files are being read from a graphical interface, use graphical_selection as default parsing
boxplot	Do not sort classes by name - keep in same order as what was passed in (so user can change order if they want) Fix for bugs associated with incorrect length of input cls and/or with numeric input cls when columns being combined
browse	Fix bug for 2014a, clean up combo box code, fix combo box code that was getting called on window button motion. Add test before update.
bspcgui	fix for errors in options settings (wrong field name and misspelled function name)
coadd	Enable coadd settings GUI to work with multiway data Enable ALL transform methods for multiway in dataset editor Add better error trapping in polytransform to explain the method does NOT work on multiway data
crossval	New waitbar logic to improve frequency and accuracy of display (and opportunity to cancel.) Fix legend entries for plots created for multivariate y
dataset	Search: Fix for error thrown when vector accidentally given as comparison value (e.g. when user isn't done typing) Search: Allow ~=, <> and = as valid comparison operators Search: Fix for inverted logic when user uses comma (should be considered "or" not "and") Search: Fix for errors thrown when one segment returns empty (and -> always return empty; or -> ignore empty)
evrimodel	Fix for calculating cross-validation on more components than asked for (max of # asked for vs. smaller of # var/samples) Consider various "virtual" fields as "true" for isfield tests Add special handling of ncomp for knn method Update ANN models to include cross-validation results fields
Hierarchical Model Builder	Fix for dragging of model into end-node. Add "Clear Canvas" option. Add support for testing T2 and Q on rule nodes based on regression and projection models.
Model Optimizer	Add "Survey Preprocessing" button, improve performance, fix duplicate checking.
evriscript	Add ANN evriscript_module
importtool	fix for error thrown when close button is used to close interface (instead of cancel) Fix offset of predefined label columns. Remove unused menu and toolbar.
modelcache	Allow export of object and linked data into a single file. Don't pester user about purging old items as much.
plsda	If user has passed only class 0 and one other class, do NOT consider class 0 "unknown"
textreadr	Add flag for graphical selection of XLS files. Add xlsb to file formats recognized as excel Trust file extension explicitly (remove support for TEXT files with excel extensions; fixes bugs on systems without excel) Make default selection "graphical_selection" Add option to control default parsing selection Better handle case when NO delimiters could be found Fix for error when no numerical values are present OR numerical and text data already match EXACTLY Change logic to assure XLS file text/data alignment is done whenever the matrices don't match (catches some odd shape cases); improve some fringe-case handling of alignment issues Improve memory and speed performance when calling importtool Improve logic to identify label columns Add maxpreviewcols and maxpreviewrows as options to control how many rows/columns are shown in import tool preview
trendtool	Instill use of figuretheme Assure trend gets updated when DSO is updated Use stored line styles when dragging markers Various bug fixes
xlsreadr	Better handle PCs without excel and MACs (don't call various functions that we know won't work)
