EigenNews - The Newsletter of Eigenvector Research Vol. 6, No. 1January 22, 2004 EigenNews is an approximately quarterly note about the happenings at Eigenvector Research, Inc., along with news of interest to the chemometrics, analytical chemistry, spectroscopy and process modeling/monitoring communities. (Subscribe and unsubscribe info at bottom.) IN THIS ISSUE: 1) Upcoming Short Courses for 2004

6) How did I get on this list? - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Process Chemometrics, our popular 3 day, hands-on course, will be held April 7-9, 2004, in Washington, DC. This course is targeted towards scientists and engineers who need to use chemometric methods in the process environment, and is especially well suited for those involved in PAT in the pharmaceutical industries. For more information, including course and venue description, please see: Process Chemometrics, April 7-9, 2004 The MathWorks (makers of MATLAB) will be teaching MATLAB Fundamentals on April 5-6, just prior to our DC Process Chemometrics course and in the same facility. Registration will be handled by The MathWorks. Process Chemometrics will also be held in Copenhagen, DK, on June 2-4, and will be followed by Applied Multi-way Analysis, June 7-10. Rasmus Bro will be joined by Eigenvector’s Barry Wise to lead the courses. Applied Multi-way is aimed at scientists who must deal with data logically arranged as 3 dimensional or higher arrays, including hyphenated instruments such as GC/MS and batch process data. Process Chemometrics, Applied Multi-way, June 2-10, 2004 Chemometrics without Equations will be followed by Advanced Chemometrics, June 21-25 in Seattle, WA, USA. Chemometrics without Equations is designed for those who wish to explore the problem solving power of chemometric tools by are discouraged by the high level of math found in many texts. The Advanced course is aimed at scientists and engineers who collect data from evolving systems, hyphenated instruments such as GC/MS, and multivariate images. Chemometrics w/o Equations, Advanced Chemo, June 21-25, 2004. Look for additional course offerings this fall at CAC (Lisbon, Portugal), FACSS (Portland, OR), and EAS (Somerset, NJ). 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, multivariate image analysis and multi-way analysis.

Try it out! We’ve made a fully functional (time expiring) demo available on-line. The demo gives you a month to use all the power of PLS_Toolbox 3.0. Get the demo here. PLS_Toolbox 3.0.4 Update Now Available We continue to refine and improve PLS_Toolbox with the latest update, 3.0.4. This small update fixes a couple minor bugs. Registered PLS_Toolbox 3.0 users can get it in the download area using their assigned username and password. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - 3) Eigenvector Welcomes New Staff Member Scott Koch Eigenvector Research is pleased to announce the addition of a new member to our staff. Scott Koch comes to us with a background in chemistry and the development of scientific software applications. Scott’s job title is Software Engineer, but he has a wide variety of experience. Our favorite part of his resume was "PSIA Level II Certified Ski Instructor: Possessed an uncanny ability to coax terrified children and adults down steep terrain and back onto chair lifts." The addition of Scott to our staff will allow us to accelerate development of PLS_Toolbox and better serve our clients needs for custom software solutions. Welcome, Scott! For more about Scott, please see his resume. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - 4) PLS_Toolbox User Tip: Options for Options Many PLS_Toolbox 3.0 functions have options which modify their behavior. Typically, options are changed by passing an options structure (See "New Features and Release Notes" in the PLS_Toolbox manual and our web site's FAQ, http://software.eigenvector.com/toolbox/3_0/faq/?options ) Here's two other hints on using Options: * One-liners: You can easily combine a call to a function and select your options-of-choice all at once! Using Matlab's "struct" command, you can modify just the options you want to change right inside the function call. For example, to call the PLS function with plots and command window display turned OFF, you could use the command: >> model = pls(x, y, ncomp, struct('plots','none','display','off')); Note that the options are defined in pairs: 'optionname','value' . For more information please see the FAQ. * Do It Your Way: You can completely avoid the use of options structures by changing the default value for any option in any PLS_Toolbox function. This is done through the PLS_Toolbox command "setplspref". For example, the following commands could be used to turn off the default plotting or display functionality of the PLS function: >> setplspref('pls','plots','none')
%turn off plots in pls The setplspref settings are remembered from one Matlab session to another. This is very useful to make a semi-permanent change to the default behavior of any function without having to continually specify an options structure each time the function is called. You can read more about setplspref on our web site FAQ. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - 5) Meeting and Workshop Calendar The following conferences and workshops should be of interest to chemometricians, analytical chemists and process engineers. If you have a meeting you'd like to list in the next EigenNews, please drop a line to bmw@eigenvector.com

If you are on this list, it means that you have corresponded with us, gone to one of the same meetings, or have published information about yourself (such as a web page) suggesting that you have an interest in chemometrics, analytical chemistry, spectroscopy, or chemical process modeling and monitoring. In other words, we had some reason to believe that you might actually be interested in receiving this newsletter.
