Updates to version 3.3 March 2017
-----------------------------------------
Activated choice of STL trend fitting.
Changed STL trend stiffness to 3.0 as default, and added button for changing it in TSM_GUI.
Added two new methods for setting SOS and EOS: relative amplitude and STL trendline crossing.
Added two new seasonality parameters: value of SOS and value of EOS.
Changed the settings file format.
Added several checks on seasonality consistency.
Relaxed checks on no. of missing values in input data.
TSM_GUI: Added legend; changed checkboxes for fitting methods into list. Last browse folder now remembered.
TSF_seas2image: The method now looks for a season defined on the maximum rather than SOS/EOS. This results in fewer missing data points.
Fixed bug in parallell processing of large files.
Fixed issues with NaN in image input files.
Various cosmetic fixes.

Updates to version 3.2
----------------------------------------
Runs on Windows 64 bit and Linux 64 bit machines.
TSF_menu: Now starts with TIMESAT or timesat commands (in Matlab mode), removed TSM_process.
(command can still be invoked from the command line).
TSF_process: Added parallel processing mode.
TSM_settings: Modified settings file format for increased flexibility.
TSM_GUI: Updated all graphics to work with the Matlab 2014b graphics engine, increased speed of some plotting routines, 
added new zooming tools. Ascii files with NaN data are now accepted. 
TSF_seas2time: Increased speed, removed memory limitation, changed format to scientific notation.
TSM_settings: fixed several minor errors.
TSM_imageview: fixed errors with qualitative legend, updated histogram function (works with Matlab 2014b or later).
Fixed several minor bugs in various routines.
Updated the manual.

Updates to version 3.1.1
---------------------------------------
Corrected TSF_seas2img and other Fortran programs to correctly read command line arguments (win + Linux)
Add option for debugging TSF_fortran at crash.
Renamed timesat.m to TIMESAT.m (required with Matlab v. 2012)
Updated the manual

Updates to version 3.1
---------------------------------------
Works on Windows 32 bit and Linux 64 bit systems, with or without Matlab
All Fortran programs now take command-line arguments for batch processing of data
Most GUI windows are resizable
Improved zoom and pan abilities in GUI
TSM_printseasons writes to ASCII file
Updated TSM_menu so that Fortran path is automatically identified.
Fixed minor bugs in TSM_menu
Increased string length of file names in Fortran programmes to 300 chars.
TSF_fit2time now prints row and column for each output series
Added TSF_merge: merges TIMESAT output files by column or by row
Added indexing of output files for faster access
Improved error messages for missing image files
Added function for merging data files: TSF_merge
Added function for exploring data files: TSM_fileinfo
Removed TSF_readheader (redundant)
Fixed various runtime errors
TIMESAT now can use paths with blank spaces

Updates to version 3.01
----------------------------------------
April 2010: Error fixed in TSM_GUI regarding reading of 2-byte binary big-endian data.

Updates to version 3.02
----------------------------------------
June 2010: Errors fixed in TSF_process and TSM_process regarding processing of data without weights.
