GenEx 5.0.1 - Release notes
The first release of GenEx 5
includes not only bug fixes but also completely new analyses and new
features.
New analyses
The optimum number of subject, sample, RT,
and qPCR replicates can be estimated with the Experimental Design
Optimization.
The calculations are based on data from either a pilot study or
estimated variance contributions for each step. The variance for the
design is minimized while keeping under the given budget.
Analysis of variance for one and two
factors (One-way ANOVA, Two-way ANOVA) has been
implemented to estimate significant differences between more than two
groups. Both include the post hoc tests Tukey-Kramer procedure,
Bonferroni's test, and Dunnett's
test.
Nested ANOVA
is used to indicate significant differences of between more than two
groups in a nested experimental design, but can also be used to
investigate the variance contribution for each level in the design.
Support vector machine (SVM)
is a new method found under the Networks analysis tab in the Enterprise
package. It is a classifying method that, based on already classified
samples, builds a model that is can be used to classify unknown samples.
Partial least square (PLS)
is a calibrating method that is found under the Regression analysis tab
in the Enterprise package. Based on known samples, it builds a model
that calibrates unknown samples.
New
features
Artificial neural network (ANN) has a new
simple interface, but still offers the same options under advanced
settings.
The entire help file have been updated with
new texts and pictures.

Company
MultiD
Analyses AB was the first company with focus on multidimensional data
analyses. It was founded in 2001 by leading scientists and software
engineers from Swedish top universities who discovered that
3-dimensional data may under certain circumstances be decomposed into
contributions from component specific contributions without making
non-trivial assumptions. This opens totally new possibilities to
analyze test samples and study chemical equilibrium, and it was
considered one of the most important discoveries in analytical
chemistry during the 1990-ies.
Our goal is to develop and sell software for analyses of
multidimensional data. Our world unique product, DATAN, based on
proprietary technology, is the most advanced software to analyze
spectroscopic data. Our second unique product, GenEx, is the most
advanced software available to analyze real-time PCR gene expression
data.
Our main competences are in the areas of spectroscopy, fluorescence
detection, data and numerical analysis, chemometry, computing, software
engineering, and real-time PCR.
