The lipidomics standards initiative and LIFS will participate in the HUPO-PSI Spring Meeting 2018, April 18th - 20th, Heidelberg, Germany.

A session on Friday will be dedicated to requirements for lipidomics data standardization. Please get in contact, if you would like to join either in person or via Google Hangouts: Join the session.

 

Meet the LIFS consortium members at Analytica 2018, April 10th - 13th, Munich, Germany.

We will present our latest advancements in the Multiomics and BIG DATA Tools for OMICS tracks, focusing on the integration of Lipidomics and Proteomics data.

See you in Munich!

During last week's 7th International Singapore Lipid Symposium, organized by Prof. Markus R Wenk, the Lipidomics Standards Initiative (LSI) was officially launched by Dr. Kim Ekroos and PD. Dr. Gerhard Liebisch.

The aim of the LSI is to define standards for protocols, reporting and data exchange formats in lipidomics.

Stay tuned for more information on the LSI and how to get involved during the next months.

Today, we are very pleased to announce the SpeCS v.0.6 release which applies the spectral comparison score (SCS) algorithm score LMs in relation to their structural similarity enabling a well-defined quality control approach for PRM based quantitation. The score is based on the Spearman’s rank correlation between fragment intensities in the query and library as well as the number of matched fragment. To automatize the scoring the software “SpeCS” was developed to

1) process raw peak lists,

2) generate customized spectral libraries,

3) perform SCS calculations, and

4) help to identify quantifier ions.

A set of filters can be employed to delete background signals and/or select only fragments that fit the compositional constraint of CnH3/2n-yOz (n=4,5,6…22; y: 0,1,2; z=0,1,2..5).
