02/18/2026, 9:55 AM--nipt and included female and male fetus NIPT samples in the cohort. However, in the resulting `.npz`:
norm["has_male"]
returns False.
I’m also trying to identify the blacklist (masked bins) genomic coordinates — i.e. the regions excluded across all samples in the reference. Does anyone know where these are stored in the .npz or how to extract them?
Has anyone seen has_male=False despite male fetus samples in the cohort? Any hints appreciated 🙏Laura Helou

02/18/2026, 10:58 AM--nipt then :
if not args.nipt:
if genders.count("M") > 4:
<http://logging.info|logging.info>("Starting male gonosomal reference creation ...")
...
else:
logging.warning(
"Provide at least 5 male samples to enable normalization of male gonosomes."
)
args.nipt = True
It is why!
