# mzID ![]( ![]( Release: ![]( Devel: ![]( mzID is a package that allows parsing of mzIdentML files. The mzIdentML file format has been created by [HUPO]( as a standardized format for collecting data from peptide identification analyses based on LC-MS type experiments. The parser is kept bare bone in order to make it as general as possible. mzID is part of [Bioconductor]( and can be installed through there. ### Main Features * `mzID(filename)` parses the mzIdentML file at the location specified by filename into an mzID object * `flatten(mzID_object)` flatten the content of the mzID object into a data frame with a row for each psm * The parser is written to support the multitude of different ways peptide identification can be performed and thus be recorded in the mzIdentML format * Defines a class to handle a collection of identification results efficiently * Relies heavily on the `XML` package (which uses libxml2) for parsing * Respects the fact that peptide identification results are not inherently tabular in format. The mzID class contains several different classes each handling different part of the analysis data * The parser is being optimized for speed within the bounds of needing to be general for all mzIdentML files. This means that a parser only handling a very specific analysis pipeline could likely be faster, but still the parser is fairly fast ### Roadmap * Make the parser software aware, so that it can create more beautiful output based on the software used in the analysis * Performance improvements
