Human Genome Assembly GRCh38.p9
Information on tiling path files (TPFs) for the assembly is available at TPF Overview.Other assembly versions:
Chromosome lengths are calculated by summing the length of the placed scaffolds and estimated gaps.
Total lengths are calculated by summing the length of the sequenced bases and estimated gaps.
N50 is a measure of contiguity. 50% of the bases reside in a scaffold of this length or greater.
Ungapped lengths are calculated by summing the length of sequenced bases only. 'Ns' are excluded.
Spanned gaps are found within scaffolds and there is some evidence suggesting linkage between the two sequences flanking the gap. Unspanned gaps are found between scaffolds and there is no evidence of linkage.
