==New Features in Solo and PLS_Toolbox==
__TOC___
==Importing / Exporting==


===[[Modelselectorgui | Hierarchical Model Builder]]===
[[faq_concatenate_multiple_files|How do I concatenate multiple files into a single DataSet?]]
* New graphical interface to build Hierarchical Models based on [[Modelselector | Model Selector]] models.
* Allows building of complex classification trees, local model selectors, and input/output filters and tests.
* Branch decisions based on classification models, regression models, decomposition models, or tests on raw input variables.
* Output model predictions, fixed strings or numerical values, or throw errors for each branch.
* Drag and drop models and other objects from the Model Cache, workspace, or file system.
* Compatible with Solo_Predictor for immediate use in on-line applications.


===[[Modeloptimizergui | Model Optimizer]]===
[[faq_create_multivariate_image_from_separate_images|How do I create a multivariate image from separate images?]]
* Added ability to [[Modeloptimizergui#Survey_Preprocessing | automatically survey]] over preprocessing settings.
* Improved support for PLSDA and SVMDA, added support for new ANN models.
* Improved handling of options and modeling errors.


===Artificial Neural Networks===
[[faq_export_PCA_scores_and_loadings_to_text_file|How do I export PCA scores and loadings to a text file (to read into MS Excel, for example)?]]
