Genomic Position Converter
hg19 to hg38 and vice versa
by Ivano Zara
This program derives the correspondences between the different genomic releases,
using the 'hg19ToHg38.over.chain and hg38ToHg19.over.chain' file of the UCSC,
where the alignment data of the different genomic sequences are reported


Genomic position converter
The conversion is performed only if a valid alignment is found on the same chromosome

Warning, some particular cases

Discordant data is sometimes obtained from the genomic alignment files (hgxxtoHgxx.over.chain).
Here are some examples. By clicking on them you can see the discrepancies.

from hg19 Chr1:1582862      from Hg19, two different positions point to the same position in hg38
from hg19 Chr1:325635      there is a conversion from hg19 to hg38 but not the reverse
from hg19 Chr1:325139      there is a conversion from hg19 to hg38 but not the reverse
