replace_regex

replace_regex performs pattern-based string replacement using regular expressions to modify and standardize text data for preprocessing and formatting of biological datasets within Galaxy workflows.

Key Features:

• String replacement: Searches text using regular expressions and replaces matches with user-specified strings to clean and standardize biological data.
• Integration with Galaxy (including Galaxy@Pasteur): Executes replacements within Galaxy-managed workflows and can run on high-performance computing clusters for scalable processing.
• API and Bioblend support: Invokes and controls replacement operations programmatically via the Galaxy API or the Bioblend library.

Scientific Applications:

• Data preprocessing in metagenomics (MetaGenSense): Standardizes sequence identifiers and annotations prior to downstream metagenomic analysis.
• Phylogenetic analysis (NGphylogeny.fr): Formats and normalizes input data files to ensure compatibility with phylogenetic software.

Methodology:

Defines a regular-expression "pattern to search" and replaces each occurrence with a user-specified "replacing string"; this process is automated and integrated into Galaxy workflows.
