Release Notes Solo Predictor Version 3 0

Changes in Version 3.0

Version 3.0 of Solo_Predictor was released in January 2014.

Packaging and Compatibility Changes

• Updated to be compatible with PLS_Toolbox/Solo 7.5
• Updated libraries to be completely compatible with all versions of Windows (MAC and Linux compatability unchanged) and to improve speed and memory performance.

NOTE: Because of this change, there will be no "updater" offered for the transition to Solo_Predictor 3.0. The new libraries which this version is based on require complete uninstall/reinstall.

Solo Scripting Changes

• Full support for Hierarchical ModelSelector Models
• Revise how reducedstats option is handled:
  • 'off' turns reduced statistics off (all are reported as raw statistics)
  • 'on' turns on reduced stats using the EVRIModel Objects methods (only Q and T2 fields will be reduced)
  • 'force' turns on old-style reduced statistics where the tsqs and ssqresiduals fields will be overwritten with reduced statistics (allows for backwards compatibility with scripts that access these fields directly)
• Add support for defining literal strings using only double quotes (without wrapping in single quotes) : mystr = "string"
• Add ability to use "end" in indexing to refer to the last element of a vector or matrix
• Allow writing to SPC files via :export command
• Add support for indexing into objects with . indexing when they are created (e.g. @datacache.add(x) )
• Add type cast (tcast) object for use in scripts - allows switching between different data types
• Added BWTek laser (bwteklaser) and spectrometer (bwtekspectrometer) objects to access and control B&W Tek spectrometers
• Add PDF Report (pdfreport) object to generate PDF-formatted reports
• Add evriarchive object as semi-persistent object storage mechanism
• Improve behavior and speed in importing strings and throwing errors on file import problems
• Add :login :token :logout and :timeout functions for use with new authentication option (see Server Changes below)
• No longer throws error when obvious STRING evaluates to empty (allows: "" as valid import)

Server Changes

• Add option to require authentication before use of socket connection (web or otherwise)
• Tune up tickle timeout behavior and disable by default
• Additional diagnostics on refused http requests
• Allow use of $tempdir in writefilefolder setting to specify the system/user temporary directory

Web Interface Changes

• Add user authentication/management support
• Add significant configuration options and additional hooks to allow more customizable applications
• When new data is added to datacache object, make sure it is re-sorted into date order
• Add new "loader" html which can be used to start a browser and wait for Solo_Predictor to start up and start serving files (when the server starts, it will automatically load the page we're waiting for)
