Hg38 canonical genome

Hello, I checked the galaxy tutorial for atac-seq and realized that it suggests to use Hg38 canonical genome for human (bowtie2). I wonder which would be its equivalent to NCBI human genome assembly? and is there a specific reason to use the canonical versus GRCh38.p14 for instance?

Hi @Urzula_Franco
Canonical version of the hg38 assembly contains only main chromosomes (autosomes, X, Y) and mitochondrial sequence. The whole assembly also contains unplaced and unlocalised contigs. .p14 refers to a patch. Patches do not disturb chromosome coordinates.

Hope that helps
Kind regards,
