The consistent processing of such data necessitates that two major challenges are met: (1) separating signal from noise, i.e. The choices made are highly variable between studies, biasing the sub-codon resolution or discarding excessive amounts of data, which makes it challenging to compare results in the literature.

In particular, most studies rely on manual selection of read lengths and manual P-site determination. A significant bottleneck is that of reproducibility and interpretation. While the assay itself has been partially standardized, the processing of data has not. Since its development, the technique has been widely adopted and inspired a diverse range of studies on translational regulation. Ribosome profiling provides the first opportunity to monitor the behavior of translating ribosomes on a transcriptome-wide scale. The tool is freely distributed as a Python package, with additional instructions, tutorial and demo datasets available at. We therefore anticipate that Shoelaces can aid researchers by automating what is typically performed manually and contribute to the overall reproducibility of studies. Shoelaces stores all processing steps performed in an XML file that can be used by other groups to exactly reproduce the processing of a given study. Shoelaces streamlines ribosome profiling analysis offering automation of the processing, a range of interactive visualization features and export of the data into standard formats. We process 79 libraries and show that studies typically discard excessive amounts of quality data in their manual analysis pipelines. Shoelaces provides both a user-friendly graphical interface for interactive visualisation in a genome browser-like fashion and a command line interface for integration into automated pipelines. The specific codon under translation (P-site) is determined by automatic offset calculations resulting in sub-codon resolution. Based on periodicity, favoring enrichment over the coding regions, it determines the read lengths corresponding to bona fide ribosome protected fragments.

We present Shoelaces, a toolkit for ribosome profiling experiments automating read selection and filtering to obtain genuine translating footprints. The data obtained with different variations of this assay is typically manually processed, which has created a need for tools that would streamline and standardize processing steps. The emergence of ribosome profiling to map actively translating ribosomes has laid the foundation for a diverse range of studies on translational regulation.
