1) Upcoming Short Courses

Escape the winter doldrums and join Neal Gallagher and Don 
Dahlberg in San Diego, California, for Chemometrics Without 
Equations (or Hardly Any) at the Sixteenth International 
Forum on Process Analytical Chemistry. This hands-on course 
will be taught on January 21-22, just prior to the IFPAC 
conference. The course will concentrate on two areas of 
chemometrics: 1) exploratory data analysis and pattern 
recognition, and 2) regression. Participants will learn to 
safely apply techniques such as Principal Components Analysis 
(PCA), Principal Components Regression (PCR), and Partial 
Least Squares (PLS) Regression. Examples will include 
problems drawn from process monitoring and quality control, 
predicting product properties, and others.

Eigenvector returns to Chelan, WA for Intermediate and 
Advanced Chemometrics with PLS_Toolbox, June 10-13, 2002. 
The course will be held at historic Campbell's Resort on 
Lake Chelan. The four day, hands-on course will start with 
pattern recognition and regression methods (PCA, PCR, PLS). 
Example problems will illustrate use of the methods with 
the new PLS_Toolbox 3.0 (coming soon!). The advanced section 
of the course will explore how multi-way methods can be used 
for investigating and modelling chemical systems, as well as 
for multivariate statistical process control. Aspects of 
multivariate image analysis (MIA) will also be covered. Here 
is your chance to update your chemometrics skills AND visit 
beautiful Lake Chelan. 

Need chemometrics training at your site? Eigenvector has a 
rapidly expanding curriculum available. In addition to the 
courses listed above, we have courses that focus specifically 
on process monitoring, inferential sensors for use in process 
control, and SIMULINK. Write to bmw@eigenvector.com for 
more information.

2) New Eigenvector Associate Don Dahlberg

Eigenvector is pleased to welcome our newest associate, Don 
Dahlberg, Professor Emeritus at Lebanon Valley College, 
Pennsylvania. Dr. Dahlberg is a charter member and past 
president of the North American/International Chemometrics 
Society. Don traces his chemometric roots to 1988 sabbatical 
with the Center for Process Analytical Chemistry at the 
University of Washington. Don was exposed to Bruce Kowalski's 
chemometrics course and was hooked. Don's primary expertise 
is in chemometric education and applications in food analysis. 
His education expertise will be utilized in his first short 
course with Eigenvector, Chemometrics without Equations (or 
Hardly any). Welcome aboard, Don!

3) PLS_Toolbox News

We're hard at work creating the next version of PLS_Toolbox, 
version 3.0. PLS_Toolbox 3.0 will feature improved interfaces 
for the most commonly used chemometric tools, and an expanded 
variety of modelling methods. Expect to hear from us in the 
next couple months. Until then, PLS_Toolbox 2.1.1 for MATLAB 
5.2 through 6.1 is available, and if you buy now, you'll get 
a free upgrade to PLS_Toolbox 3.0 when it ships.

4) DataSet Standard Data Object version 3.01

MATLAB supports a variety of data types such as double arrays, 
structures and cell arrays. Until now, however, there has been 
no standard way to associate all the parts of a data set that 
go together, including the sample and variable labels, class 
variables, time and wavelength axes, etc. In order to 
facilitate data set handling, Eigenvector has created the 
DataSet Standard Data Object. When added to a MATLAB installation, 
DataSet creates a new object in MATLAB that integrates all of 
the separate components associated with a data set into a single 
variable in the MATLAB workspace. 

The current version of DataSet is 3.01, released October 18, 2001. 
The DataSet object is available from our web site. We hope that 
MATLAB users everywhere will use it when writing routines that 
are data intensive. Existence of the object will greatly enhance 
the exchange of data sets, the translation of data sets between 
file types (see next article) and the handling of data sets within 
MATLAB. Future versions of PLS_Toolbox will take full advantage of 
the DataSet object. To download DataSet or for more information, 
go to the DataSet page.

5) SpectraExpress for Translating Spectral Data Files

Probably the most frustrating thing about chemometric analysis is 
the problem of translating data formats into your analysis tool of 
choice. Help is on the way! The folks at Harvie Custom Computers, 
Inc. (HCCI) have developed a product, SpectraExpress, which can be 
used to move data between several common formats, including MATLAB, 
Excel, and GRAMS .SPC files. Future versions of SpectraExpress will 
also support the DataSet Standard Data Object. For more information, 
please contact HCCI.

6) MATLAB for MacOS X Petition

Would you like to see MATLAB return to the Mac? An on-line petition 
has been started which asks The MathWorks to bring MATLAB to Mac OS X. 
The petition can be found at:


If you are a Mac user, used to be a Mac user and would like to be again, 
or someone who can appreciate the benefits of a Unix based operating 
system which also supports a wide variety of common productivity 
applications, please consider signing the petition.

FYI, up through version 2.0, PLS_Toolbox was developed almost entirely 
on Macs!
