Contiguity
N50
CC ratio (contig/chromosome ratio)
Completeness
BUSCO
Complete organelle genomes
Correctness
Base-level error rate
Structural error: collapse, inversion, false duplication, chimeric joins

A proposed metric set for evaluation of genome assembly quality (https://doi.org/10.1016/j.tig.2022.10.005)
• Length
. contig (scaffold) N50 size, N90 size, total length, CC ratio;
• Accuracy
. Compare to BAC sequence
. Compare to EST or transcriptions (denovo assembly with RNA-seq);
. RNA/DNA Mapping and Coverage (NGS & TGS), and CRAQ;
. Distribution of GC content and GC-Depth;
. Using the LTR Assembly Index (LAI);
. k-mer based assembly evaluation (merqury);
. Compare gene parameters: BUSCO, CEGMA;
. Check the Telomeres & Centromeres & rDNA sequence (T2T level);
