+# SamestrGal for shared-strain detection in metagenomes
+
+This workflow processes paired-end shotgun metagenomic sequencing reads from multiple samples. It performs the following steps:
+
+- **Preprocessing**: Quality trimming and host read removal using KneadData
+- **Taxonomic profiling and marker-based alignment**: MetaPhlAn4 or mOTUs for taxonomic classification and marker based alignment
+- **Strain detection**: SameStr tools identify strains across samples and compute pairwise strain comparisons using Maximum Variant Profile Similarity (MVS) scores.
+
+## Inputs
+
+- **Raw Reads**: A collection of paired-end FASTQ files from one or more samples to compare
+- **Run MetaPhlAn**: Boolean parameter (default: true) that enables MetaPhlAn-based strain detection
+- **Run mOTUs**: Boolean parameter (default: false) that enables mOTUs-based strain detection
+
+## Outputs
+
+ - **MetaPhlAn results** (if enabled): SNV profile summary statistics, taxon counts, strain events, and co-occurrence tables
+ - **mOTUs results** (if enabled): SNV profile summary statistics, taxon counts, strain events, and co-occurrence tables
