Uses SIRIUS to find features.
findFeaturesSIRIUS(analysisInfo, verbose = TRUE)A data.frame with Analysis information.
If set to FALSE then no text output is shown.
An object of a class which is derived from features.
This function uses SIRIUS to automatically find features. This function is called when calling findFeatures with
algorithm="sirius".
The features are collected by running the lcms-align SIRIUS command for every analysis.
The MS files should be in the mzML or mzXML format. Furthermore, this algorithms requires the
presence of (data-dependent) MS/MS data.
The input MS data files need to be centroided. The convertMSFiles function can be used to
centroid data.
findFeaturesSIRIUS uses multiprocessing to parallelize
computations. Please see the parallelization section in the handbook for
more details and patRoon options for configuration
options.
Note that for caching purposes, the analyses files must always exist on the local host computer, even if it is not participating in computations.
