ALT-Aware Liftover File Options

The following options control See ALT-Aware Hash Tables for more information on building a custom liftover file.

 

--ht-alt-liftover

The --ht-alt-liftover option specifies the path to the liftover file to build an ALT-aware hash table. This option is required when building from a reference with ALT contigs. SAM liftover files for hg38DH and hg19 are provided in /opt/edico/liftover.

--ht-alt-aware-validate

When building hash tables from a reference that contains ALT-contigs, building with a liftover file is required. To disable this requirement, set the --ht-alt-aware-validate option to false.

--ht-decoys

The DRAGEN software automatically detects the use of hg19 and hg38 references and adds decoys to the hash table when they are not found in the FASTA file. Use the --ht-decoys option to specify the path to a decoys file. The default is /opt/edico/liftover/hs_decoys.fa.

--ht-suppress-decoys

Use the --ht-suppress-decoys option to suppress the use of the decoys file when building the hash table.
