Therefore, new methods for automated, fast, reproducible, and accurate data processing and dereplication are required. Here, we present UmetaFlow, a computational workflow for untargeted metabolomics that combines algorithms for data pre-processing, spectral matching, molecular formula and structural predictions, and an integration to the GNPS workflows Feature-Based Molecular Networking and Ion Identity Molecular Networking for downstream analysis. UmetaFlow is implemented as a Snakemake workflow, making it easy to use, scalable, and reproducible. For more interactive computing, visualization, as well as development, the workflow is also implemented in Jupyter notebooks using the Python programming language and a set of Python bindings to the OpenMS algorithms (pyOpenMS). Finally, UmetaFlow is also offered as a web-based Graphical User Interface for parameter optimization and processing of smaller-sized datasets. UmetaFlow was validated with in-house LC-MS/MS datasets of actinomycetes producing known secondary metabolites, as well as commercial standards, and it detected all expected features and accurately annotated 76\% of the molecular formulas and 65\% of the structures. As a more generic validation, the publicly available MTBLS733 and MTBLS736 datasets were used for benchmarking, and UmetaFlow detected more than 90\% of all ground truth features and performed exceptionally well in quantification and discriminating marker selection.}, language = {en} } @inproceedings{GesingKacsukKozlovszkyetal.2011, author = {Gesing, Sandra and Kacsuk, Peter and Kozlovszky, Miklos and Birkenheuer, Georg and Blunk, Dirk and Breuers, Sebastian and Brinkmann, Andre and Fels, Gregor and Grunzke, Richard and Herres-Pawlis, Sonja and Kr{\"u}ger, Jens and Packschies, Lars and M{\"u}ller-Pfefferkorn, Ralph and Sch{\"a}fer, Patrick and Steinke, Thomas and Szikszay Fabri, Anna and Warzecha, Klaus Dieter and Wewior, Martin and Kohlbacher, Oliver}, title = {A Science Gateway for Molecular Simulations}, series = {EGI (European Grid Infrastructure) User Forum 2011, Book of Abstracts}, booktitle = {EGI (European Grid Infrastructure) User Forum 2011, Book of Abstracts}, pages = {94 -- 95}, year = {2011}, language = {en} } @inproceedings{GesingGrunzkeBalaskoetal.2011, author = {Gesing, Sandra and Grunzke, Richard and Balasko, Akos and Birkenheuer, Georg and Blunk, Dirk and Breuers, Sebastian and Brinkmann, Andr{\´e} and Fels, Gregor and Herres-Pawlis, Sonja and Kacsuk, Peter and Kozlovszky, Miklos and Kr{\"u}ger, Jens and Packschies, Lars and Sch{\"a}fer, Patrick and Schuller, Bernd and Schuster, Johannes and Steinke, Thomas and Szikszay Fabri, Anna and Wewior, Martin and M{\"u}ller-Pfefferkorn, Ralph and Kohlbacher, Oliver}, title = {Granular Security for a Science Gateway in Structural Bioinformatics}, series = {Proc.
