Tapestri Designer supports human genome hg19 (GRCh37) and mouse genome mm10 (GRCm38). If you have hg38 coordinates, convert them to hg19 using the UCSC liftover tool.

For example, if you are interested in designing to a gene on chromosome 1 in the region 11,205,824 to 11,207,703, enter it as either: 

chr1:11205824-11207703 

1:11205824-11207703 

Chr1:11205824..11207703

Important: Review the position of the entered coordinates in the completed design to ensure they are correct.
