 The user interface for NTSYSpc has been redesigned to be easier to
use (see the sample screen shots). There is now a User folder in which you
can place the icons for the modules you use most frequently.

 Input file formats have not changed  except for a small change
in Excel files. Matrices in Excel XLS files can now be read directly by the
computational modules  there is no longer a need to import them using the
NTedit program. All matrix types, rectangular, symmetric, etc., are now
supported.

 The NTedit program has been revised to include a text mode in
which very large ASCII files can be edited (files up to 16MB with line
lengths up to 32K). Standard cut, copy, paste, and other text editing
commands are supported.

 Graphics have been greatly improved and can be called directly from many of the computational modules by the use of speed buttons on a toolbar. The entry forms for the graphics programs have also been simplified since the graphic options are now available from option dialog boxes. You can now control the titles, scale, colors, fonts, line widths, etc. of most aspects of the plots.
NTS files can now be loaded into the editor by just doubleclicking on them
in the Windows Explorer or by rightclicking on them and using the Windows
"Send to" feature.

 New computational modules have been added:
 AUTOREGR  Fits an autoregressive model. Used in spatial and
phylogenetic "autocorrelation" studies. 
 PROCRUSTES
 Procrustes superimposition of coordinates of 2D or 3D landmarks on
specimens or superimpositions of multivariate ordinates of any
dimension. Option to ignore reflections. 
 PROCPLOT
 2D and 3D plots of the results of a Procrustes superimposition. 
 FOURPLOT
 Plot outlines and estimated outlines from the FOURIER module. 
 MULREG
 generalized multivariate multiple regression. Can be used to perform
simple bivariate regression, multiple regression, multivariate
regression, and generalized leastsquares regression (as used for the
comparative method). 
 PLOT  Plot one or more columns of a rectangular
matrix against a selected column. Points can be given different symbols
and connected by lines 

 Many computational modules have been revised:
 CONSEN
 Input trees can be in the nexus file format. 
 COPH
 Input tree can be in the nexus format. Path length (additive)
distance matrix and phylogenetic covariance matrix can be computed in addition to
the usual ultrametric distances. 
 CVA
 Can compute canonical variates scores for individual observations. 
 FOURIER
 Many changes were made to make this module more useful. Linked to
the new FOURPLOT module for direct viewing of the results. 
 MOD3D
 Rewritten to provide interactive 3D rotation (drag with the mouse)
and better axis labeling. Different symbols can be given to different
points. 3D biplots can be produced. 
 MXCOMP
 The SmouseLongSokal (1986) 3way Mantel test has been added to
allow one to study the association between two distance matrices while
holding the effects of a third matrix constant. 
 MXPLOT
 Points can be given different symbols. 2D biplots can be produced. 
 NJOIN
 Completely rewritten to greatly increase its speed. Larger datasets
(i.e., more than 500 OTUs) can now be processed. Results can be saved in nexus
file format or as an extended NTS tree format that allows for unequal heights
of the OTUs in the tree. An option has been added for unweighted
neighborjoining trees. 
 OUTPUT
 Supports Excel files and the new tree formats. 
 POOLVC
 Allows missing values in data when computing the mean and covariance
matrices. 
 TPSWTS
 Modified to include a Procrustes superimposition and computation of
a consensus configuration. 3D uniform
component can now be computed. 
 TREE
 Can now plot trees with unequal heights of the OTUs. Nexus tree
files can be read. 

 Graphics have been improved to include interactive rotation in the
3D plots. Plot options can now be saved and restored. Groups of points can
now be given different symbols in MOD3D and MXPLOT. When MXPLOT is called
directly by SVD, EIGEN, or PROJ the option to preserve the correct aspect
ratio is set automatically.
