Molecular fingerprints for exploring the chemical space of natural products

Posted on

We evaluated the effectiveness of multiple types of fingerprints for representing the chemical space of natural substances. The code and data to reproduce the results are also available in the study: Boldini, D., Ballabio, D., Consonni, V., Todeschini, R., Grisoni, F., Sieber, S.A. (2024) Effectiveness of molecular fingerprints for exploring the chemical space of natural products, Journal of Cheminformatics 16, 35 (2024), https://doi.org/10.1186/s13321-024-00830-3

A new metric to assess the degree of accuracy of consensus predictions

Posted on

We proposed a new heuristic metric to assess the degree of accuracy of consensus predictions. It can assist the mapping of reliability in prediction and enhance the delineation of a safe zone, where consensus predictions are expected to have better accuracy. All details are available in the following publication, have a look! We also provide data and code to calculate it, here!

Kohonen and CPANN toolbox: new release!

Posted on

A new release of the Kohonen and CPANN toolbox (4.6) is now available. In this release, GPU and CPU calculation has been improved. The Kohonen and CPANN toolbox for MATLAB is a collection of MATLAB modules for training Kohonen Maps (Self Organising Maps, SOMs), Counterpropagation Artificial Neural networs (CPANNs), Supervised Kohonen networks (SKN), XY-fused networks (XY-F). It can be downloaded here: https://michem.unimib.it/download/matlab-toolboxes/kohonen-and-cpann-toolbox-for-matlab/

Condensed Phase Membrane Introduction Mass Spectrometry (MIMS): a review!

Posted on

Membrane introduction mass spectrometry (MIMS) is a direct mass spectrometry technique used to monitor online chemical systems or quickly quantify trace levels of different groups of compounds in complex matrices without extensive sample preparation steps and chromatographic separation. Here a recent review:
