Plasma Precipitation Analysis (1)

• Download

ABOUT THE WORKFLOW This workflow was used to analyze the data in a manuscript by Mostovenko et al. (2012, submitted), comparing proteins in the precipitate with those left in solution after organic solvent precipitation. However, the workflow is generally applicable in comparisons of any binary fractionation method in proteomics, where the fractions are analyzed by liquid chromatography-tandem mass spectrometry. The workflow identifies proteins by SpectraST spectral library search and X!Ta...

Author to Wordcloud (3)

• Download

This small workflow demonstrates how to connect to and use Europe PMC (http://europepmc.org/RestfulWebService). The workflow searches the publications of an author, extracts the abstracts, counts the word frequencies and plot a wordcloud using the R package of the same name. The Rshell plot_wordcloud also applies text mining operations (transformation to lower case, removing punctuation, stripping whitespace and removing English stopwords) using the R package tm.

Simulate_Mass_Spectrum (1)

• Download

This workflow takes as input a peptide sequence and calculates the elemental composition of the peptide (Calculate_Elemental_Composition). This is then transferred as a numerical vector to the Rshell Simulate_Mass_Spectrum, that calculates the isotopic distribution using the FFT method and convolutes the theoretical (infinite resolution) distribution with a Gaussian peak shape. The building blocks can be used in any other workflows using the isotopic distribution of peptides or other molecul...

compare_pubmed_results_geographically (1)

• Download

This workflow analyzes the scientific output, as documented by PubMed, geographically. The workflow takes as input the PubMed data in XML and the ISO 3166-1 and ISO 3166-3 country lists. The XML file can contain any subset from a specific PubMed search. The XPath components extract author affiliations, and feed these to a series of Beanshell components that match these with countries in the ISO standard. This data is then fed to an Rshell using the rworldmap R package to map the affiliation ...

Visualize Geographical Bias between PubMed... (3)

• Download

This workflow analyzes the scientific output, as documented by PubMed, geographically. The workflow takes as input the PubMed data in XML and the ISO 3166-1 and ISO 3166-3 country lists. The XML files can contain any subset from two specific PubMed searches. for example for two different journals in the same field. The XPath components extract author affiliations, and feed these to a series of Beanshell components that match these with countries in the ISO standard. This data is then fed to ...

Calculate_Isotopic_Distribution (1)

• Download

This small workflow takes as input a peptide sequence and calculates the elemental composition of the peptide (Calculate_Elemental_Composition). This is then transferred as a numerical vector to the Rshell Calculate_Isotopic_Distribution, that calculates the (integer mass) isotopic distribution using the FFT method. To shift to approximate real masses (or m/z values), transpose the distribution with the difference between the integer and real monoisotopic masses (both easily calculated using ...

Retention Time Prediction with X!Tandem (1)

• Download

This workflow identifies peptides from tandem mass spectra using X!Tandem as in a standard installation of the Trans-Proteomic Pipeline (TPP, version 4.6, but earlier versions should also work). The peptide-spectrum matches are validates using PeptideProphet (also from a standard installation of TPP) and peptides with at least a probability 0.95 are used to train a linear retention time predictor (Palmblad et al., 2002), whereby retention coefficients are also derived. These indirectly provid...

Create Local Citation Graph (1)

• Download

This workflow demonstrates how to build a local citation/reference graph for a single pubilcation in PubMed. The id input is the PubMed id (pmid) for any publication in the PubMed or PMC Europe. The workflow then queries the PMC Europe Web services to get the citations and references for this publication. Two XPath parsers are used to extract the citation and reference ids, which are then combined and passed on to an Rshell that draws a Sugiyama style layered graph using the igraph package. T...

RTCalc Retention Time Prediction and Outli... (1)

• Download

This workflow takes as input a pepXML file from PeptideProphet, applied RTCalc and outputs a filtered list of peptides based on the retention time Z-scores.

Author Publications and Citations by Year ... (2)

• Download

This small workflow demonstrates how to connect to and use Europe PMC (http://europepmc.org/RestfulWebService) to count the number of publications and citations per year for one author. Two REST calls are made. First, we "searchPublications" to retrieve the bibliographic records for all published work of a single author. Then, we "getCitations" to extract the year of all articles citing the work of this author. A conditional XPath is here used to only look up citing articles for cited work, i...
