Workflow ENM Maxent workflow used for optimization (1)

Thumb
This workflow was used for the optimization of the Maxent algorithm from the openModeller toolbox (http://openmodeller.sourceforge.net/). The workflow uses 10-fold cross-validation and then calculates the average AUC, which can be used as fitness value during parameter optimization.

Workflow Ecological niche modelling workflow (28)

Thumb
This workflow takes as input a file containing species occurrence points to create a model with the openModeller Web Service. Algorithm, environmental layers and mask are selected during the workflow. The model is tested (internal test and optional cross validation external test) and then projected one or more times. All points from the input file are used to create a single model, even if there are differences in the scientific names. Cross validation calculates the mean AUC. Model projectio...

Workflow Bioclim workflow (6)

Thumb
This workflow takes as input a file containing species occurrence points to create a model with the openModeller Web Service using the Bioclim algorithm. Environmental layers and mask are selected during the workflow. Points are filtered so that only environmentally unique points are used to create the model. You can use this workflow to either filter a set of species occurrence points excluding redundant points with the same environmental conditions (you can get the result in the output "se...

Workflow BioVeL ESW DIFF Basic (4)

Thumb
this workflow is a basic version of the ESW DIFF, it computes an raster diff from GeoTIFF or ERDASImagine files and some statistics about the files and their difference without to display country borders and occurence points. For more about the input and output files see the BioVeL PSW workflow description: http://www.myexperiment.org/workflows/3647.html

Workflow Scan range splitting for untargeted metabo... (1)

Thumb
This workflow analyzes untargeted HPLC-Orbitrap measurements split into separate or alternating scan ranges. The input nodes expect OpenMS consensusXML files that were exported using TextExporter. The workflow then combines the separate scan ranges, filters them utilizing blank and QC measurements, and performs a statistical analysis.Requirements:- KNIME Interactive R Statistics Integration

Workflow BioVeL workshop reduced full workflow (1)

Thumb
The workflow is a reduced version of the main workflow. It can be used to call web services to support biodiversity research. It fetches data from GBIF. The occurrences are then used to create a model using OpenModeller, test the model and to project the model. The projection of the model is currently a "native projection" i.e. it uses the same layers as those used to create the model. The services within the workflow will allow non-native projections

Workflow BioVeL ESW DIFF - ENM Statistical Workflow... (16)

Thumb
The ENM Statistical Difference Workflow (ESW DIFF) allows the computation of the extent and intensity of change in species potential distribution through computation of the differences between two raster layers using the R statistical environment (R Core Team 2013). The difference file is computed from two input files (in this case present projection and 2050 projection) coming from the Ecological Niche Modelling (ENM) Workflow (http://www.myexperiment.org/workflows/3355). The difference bet...

Workflow ENM resolution mix - single run version (6)

Thumb
Single run version of the workflow for comparing results of two kinds of ecological niche models: one using only low resolution layers and the other using a random mix of low and high resolution layers. Users select the study region and the environmental variables considered to be the main drivers of a virtual species niche. The workflow is all based on the ENM components, which use the openModeller Web Service (OMWS). After getting initial parameters from the user, the workflow generates a r...
