rTANDEM

rTANDEM integrates the X!Tandem protein identification algorithm into R/Bioconductor to perform MS/MS-based peptide and protein identification from mass spectrometry data.

Key Features:

• X!Tandem execution: Executes the multi-threaded X!Tandem algorithm from within R to perform protein identification on MS/MS data files.
• Extended syntax and automation: Provides extended syntax and functions to launch and automate searches by manipulating X!Tandem parameters programmatically in R.
• Data conversion functions: Converts search parameters and results between X!Tandem formats and R/Bioconductor data structures for downstream analysis.

Scientific Applications:

• MS/MS-based proteomic pipelines: Supports peptide and protein identification workflows for analysis of complex biological samples using tandem mass spectrometry.
• R/Bioconductor integration for downstream analysis: Enables incorporation of X!Tandem search results into R/Bioconductor workflows for statistical processing and further bioinformatic analyses.

Methodology:

Interfaces directly with the X!Tandem algorithm, leverages its multi-threaded capabilities to handle large-scale proteomic datasets, and provides functions for parameter manipulation and conversion of search results between X!Tandem formats and R data structures.
