Journal ArticleDOI

Visualization of GC/TOF-MS-based metabolomics data for identification of biochemically interesting compounds using OPLS class models.

TL;DR: The S-plot is proposed as a tool for visualization and interpretation of multivariate classification models, e.g., OPLS discriminate analysis, having two or more classes, and an improved visualization and discrimination of interesting metabolites could be demonstrated.
Journal ArticleDOI

Chemography: the art of navigating in chemical space.

TL;DR: ChemGPS scores are comparable across a large number of chemicals and do not change as new structures are predicted, making this tool a well-suited reference system for comparing multiple libraries and for keeping track of previously explored regions of the chemical space.
Journal ArticleDOI

Assessing the performance of OMEGA with respect to retrieving bioactive conformations

TL;DR: The duplicate removal parameter was found to have the largest impact on retrieval of bioactive conformations, and the maximum number of conformations also affected the results considerably, while pre-optimizing the input structures with MMFF94s improved the results significantly.
Journal ArticleDOI

Using chemometrics for navigating in the large data sets of genomics, proteomics, and metabonomics (gpm)

TL;DR: The applicability of multivariate projection techniques, such as principal-component analysis (PCA) and partial least-squares (PLS) projections to latent structures, to the large-volume high-density data structures obtained within genomics, proteomics, and metabonomics is described.
Journal ArticleDOI

Novel Chemical Space Exploration via Natural Products

TL;DR: The chemical space navigation tool ChemGPS-NP is used to evaluate the chemical space occupancy by NPs and bioactive medicinal chemistry compounds from the database WOMBAT and property based similarity calculations were performed to identify NP neighbors of approved drugs.
