Workflow Metabolic differences in ripening of Solan... (2)

Thumb
Updated data processing workflow for metabolomics LC-MS/MS data. This workflow depends on the stable community plug-in MassCascade and KNIME plug-ins Base Chemistry, Chemistry Types & Nodes, Math Expression, and XLS Support. The workflow was run under KNIME version 2.9.2.

Workflow Integrative data mining of chemical compou... (1)

Thumb
This workflow downloads ligand data for hepatic Organic Anion Transporting Polypeptides (OATPs) from five different open sources (CHEMBL, Metrabase, USFC-FDA Transportal, IUPHAR, and Drugbank) in an semi-automatized fashion. This workflow can be adopted to any other ligand data showing an (in)activity against membrane transporter. If missing, structural file format is mapped via PubChem webservices. Pre-curated compounds are subjected to standardization procedure (Atkinson standardization scr...

Workflow Genetic Algorithms for BIOISOSTERIC Struct... (1)

Thumb
Genetic algorithm workflow to generate novel structures by recombination and mutation and that uses an ML model as a fitness function. Both the fitness function and the fingerprints modified in the model should be the same. ML model cannot have any descriptors other than given fingerprint.Reverse molecular mapping/generation is not part of this workflow and can be done by creating a large Structure-FP database.

Workflow Substructure querying | R-group decomposit... (1)

Thumb
This workflow creates maximum common substructure (MCS) out of the provided structures and then substructure mining using MCS as a structural query is performed. Obtained hits are then subjected to R-group decomposition to explore their functional groups. Optionally, physicochemical descriptors for individual functional groups can be calculated.

Workflow Scaffold Analysis | Statistical analysis o... (1)

Thumb
This workflow performs an extraction and statistical analysis of Murcko scaffolds for compounds being active against (a) different target(s). Specifically, target-wise detection of Murcko Scaffolds in active versus inactive compounds, filtering steps by removing too generic scaffold (i.e., number of rings equals to one OR number of heteroatoms in a ring is zero or one), calculating the frequency of a particular scaffold which appears frequently in the active over inactive class, applying Fish...

Workflow KNIME Workflow for RetroRules and Selenzyme (4)

KNIME Workflow for RetroRules and SelenzymeThis worflow provides an examples of retrieving the RetroRules reaction rules for some given reaction and selecting enzyme sequences using the Selenzyme tool.1. Input to the workflow: Chemical reactions expressed using public database identifiers.2. Each reaction queries RetroRules and outputs the corresponding reaction rules.3. Each reaction rule queries Selenzyem and outputs the selected Uniprot sequences for each rule.4. Resulting list of selected...

Workflow Europe PMC searchPublications and getAnnot... (2)

This workflow first conducts a search and downloads the PMIDs for all publications in PubMed and PMC that match a particular query using the Europe PMC Articles API. In a second phase, the workflow fetches the ChEBI annotations for all these publications using the Europe PMC Annotations API.

Workflow zetasizer2excel (2)

Thumb
Arrrgh! The exported data file format for the Malvern Zetasizer is insane!Row1, x1,x2,x3,x4,....,y1,y2,y3,y4,....Row2, x1,x2,x3,x4,....,y1,y2,y3,y4,....Row3, x1,x2,x3,x4,....,y1,y2,y3,y4,....This workflow imports the txt file, takes each row and reformats as table with 3 columns: Size, Intensity, Volume. Then exports the data for each row to a new tab in Excel. Or you can just use KNIME to plot and prepare reports (to do).The TableRow2Variable node allows you to name the tabs in Excel from a ...

Workflow RetroPath2.0-Mods-isomer-transformation-queue (2)

Thumb
The workflow allows one to enumerate isomers of chemical structure(s) using the isomer transformation algorithm. It is a modified version of "RetroPath2.0-Mods-isomer-transformation". It illustrates how to introduce a FIFO data structure for the source set and use it for iteratively firing rules on small chunks of structures. See [1] for details. How to useSee instructions embedded in the workflow.Usage specificationsThe workflow is compatible starting from version 3.4.1 of Kni...
