About pgatk-io

The pgatk-io library is a java framework to manipulate mass spectrometry and proteomics file formats. It has an special focus on novel file formats like Apache Spark Parquet and Json file formats for proteomics.

Main Features

  • Based on a custom build class to efficiently parse text files line by line all parsers can handle arbitrary large files in minimal memory, allowing easy and efficient processing of peak list files using the Java programming language.

  • For every implementation a Random Access and Iterable Access Reader is provided.

    • In the Random access developers can access to any individual Spectrum using the Identifier of the Spectrum or the index.
    • In the Iterable access developers can access one by one each of the spectra with the next function
