I’ve developed a Galaxy wrapper for the Bioconductor XCMS CentWave algorithm that enables peak detection on raw .mzML and .mzXML files without writing R code.

**Key Features:**

- Industry-standard CentWave algorithm
- Batch processing via Galaxy dataset collections
- Configurable PPM, S/N, peakwidth, and prefilter parameters
- Tab-separated output for downstream metabolomics workflows
