-    <description>Automated detection of intervals covered at half depth by sequenced reads</description>
+    <description>automatically identifies genomic regions with half-depth coverage based on sequencing read mappings (e.g., PacBio HiFi or Illumina short reads). These regions may reveal insights into heterogametic sex chromosomes, haplotype-specific variation, or potential assembly errors such as heterotypic duplications.</description>
