Dear chemometricians,
Thanks for participating in SSC12 at LEGOLAND in Billund, Denmark, making it a memorable event. You can find the photos from :

Conference location: Hotel LEGOLAND, Billund, Denmark
Date: 7-10 June 2011
Denmark was now the host of the 12th Scandinavian Symposium on Chemometrics (SSC12, ) held in the Nordic countries. The symposium had a strong scientific focus with a great social programme. The programme included contributed lectures, poster presentations and vendor exhibitions. As tradition offers, the prestigious HermanWold medal in gold was awarded during the conference dinner on Thursday night.
EUCHEM conference: Chemometrics Epistemology in Systems Biology (May 9-11 2011,Sweden)
Written by Johan Trygg
Systems biology has matured as a research field and includes advanced modeling of biological systems. It is partly driven by the generation of high-throughput or so called ’omics data (e.g. proteomics and metabolomics). However, it has become more and more recognized that there is a gap between data generation and biochemical interpretation. How to generate informative data and to develop data analytical tools to convert data into biochemical information?
This is the focus of this EUCHEM conference,

Invitation to SSC12 in Billund, Denmark (June 7-10,2011)
Written by Johan Trygg
Conference location: Hotel LEGOLAND, Billund, Denmark
Date: 7-10 June 2011
The first Scandinavian Symposium on Chemometrics was held in 1989 in Lappeenranta, Finland.The 11th (SSC11) was successfully held in Loen, Norway in 2009. Denmark is now the host of the 12th Scandinavian Symposium on Chemometrics (SSC12) held in the Nordic countries. The symposium will, of course, have a strong scientific focus and the programme will include contributed lectures, poster presentations and a vendor exhibition. The symposium invites speakers from adjacent scientific areas as well as young scientists to present their research.
Can we use the regression coefficient profile for selecting PLS components?
The linear model y=Xb + f is often used in chemometrics. Unfortunately, we have put too much emphasis on the importance of the regression coefficient profile b, and mistakenly assumed or believed that it should be a good estimate of the "pure profile". This is not true, and I will argue why in later editorials. But this time, I want to address an earlier question that was posed in relation to the regression coefficient profile.
The Tutorial and Editorial sections have now been updated with a link to their respective pdf files for you to download.

Wavelets in Chemometrics
In chemistry, as well in other branches of science, there is a steady trend towards the use of more variables (properties) to characterize observations (e.g. samples, molecules, proc-esses). Wavelet analysis and compression, followed by PCA or PLS and their generalizations, form a simple and practical tool, allowing computations to be made using a much-reduced set of variables, but without any loss of information.
