Wilcoxon rank sum test <i>p</i>-values comparing genome assembly metrics (<i>variable</i> column) of species for which a shift was identified to close-relative species with no shift (<i>shift_edge</i> column).

L50 (smallest number of contigs whose length sum makes up half of genome size), length of the largest scaffold in base-pairs (maxLen), median scaffold length in base-pairs (medianLen), length of the smallest scaffold in base-pairs (minLen), number of GC segments genome-wide (segmentation), N50 (sequence length of the shortest contig at 50% of the total assembly length), percentage of complete BUSCO genes (complete), number of scaffolds (seqCounts) and genome size in base-pairs (totalBases).
