At the moment I use a simple bash one-liner like the one below, but I presume there must be a cleaner way to do it with samtools/sambamba or some other tool.

```

samtools view -h -L $karyotype_bed $inputfile | grep -v decoy | grep -v HLA | grep -v _alt | grep -v chrUn | grep -v random | grep -v chrEBV | samtools view -bS - > $outfile

```
