You sequenced your genome. Now read it

Q: What is a VCF file?

Variant Call Format: the standard text file labs and sequencing companies use to list genetic positions and your letters at each one. More in VCF files explained.

Q: Can I upload whole genome sequencing data?

Yes. Drop the VCF (.vcf or .vcf.gz) as your lab sent it, at any size. Your browser reads it on your device and keeps only the few hundred markers the report needs.

Q: How long does a whole-genome VCF take?

A few minutes on a laptop for a 3 to 5 GB file, longer on a phone. A progress bar shows how far the read has got; keep the tab open until it finishes.

Q: My VCF has a dot instead of rsIDs. Will it work?

Yes. Each marker is found by its chromosome and position on GRCh37 or GRCh38, and the build is read from the file itself.

Q: Why does my VCF give no results?

Usually it is not quite a VCF of your genome: raw reads (BAM, CRAM, FASTQ) have to be turned into a VCF first, and a file on a reference other than GRCh37 or GRCh38 can’t be matched. An exome or gene panel covers only selected genes, so it finds fewer markers.

Q: What can I do with my Nebula Genomics raw data?

Download the VCF from your Nebula or DNA Complete account and drop it here for a free health report: nutrition, training, sleep and mood, each finding with its study. The file is read in your browser and never uploaded.

Q: Can I upload my Dante Labs VCF?

Yes. Take the .snp.vcf.gz (or .snp-indel.vcf.gz) from your Genome Manager profile and drop it as it is. Older Dante files on GRCh37 and newer ones on GRCh38 both work.

Q: Is this the same VCF as a contacts file?

No. A genomic VCF (Variant Call Format) lists your DNA variants; a contacts .vcf is a vCard. They share the extension, which is why your computer may offer to open your genome in the Contacts app. Drop it here instead.

Q: Is it safe to upload my VCF here?

The file is never uploaded. Your browser reads it on your device and sends only the few hundred markers the report needs, well under a megabyte, which you can delete in one click.

Q: Is the VCF analysis free?

Yes. Drop the file with no account and no card and see real findings in about a minute. The full report, the PDF and your own AI are a one-time $49, no subscription.

Drop your whole genome sequencing data from Nebula, Dante Labs or any lab and find out what your genes say about you: coffee and carbs, the training your muscles are built for, night owl or early bird, how your mood is wired. Then hand it to your own AI for a nutrition plan, a training week or a morning routine built on it.

01Whole genome

Whole genome sequencing data, read in your browser

Whole genome sequencing data from Nebula, Dante Labs, Sequencing.com or any lab: drop the raw data file as it came. No converting, no waiting, and it never leaves your computer.

Size

Any size

A 4 GB raw data file is fine. Your browser reads it in a few minutes, a phone takes a little longer.

Prep

No prep needed

Drop it as it came, zipped or not. No converting, no renaming, no ID column to fix.

Privacy

Nothing uploaded

Your raw data stays on your computer. Only the few hundred markers the report uses reach us, under a megabyte.

3.2 billionpositions in your genome

~5 millionlines in your whole genome raw data (VCF)

647markers the report reads, by rsID or position

< 1 MBreaches Helisoma: those markers, nothing else

02What you will find out

What your whole genome says about you

Your whole genome raw data holds studied markers across five areas of your life, each finding in plain words with the study behind it. Nutrition first: caffeine, milk, omega-3, alcohol, vitamins. Then training, sleep, mood and longevity.

Nutrition →

How fast you clear caffeine CYP1A2
Whether milk still sits well as an adult LCT
How well you turn plant omega-3 into EPA and DHA FADS1
Why alcohol makes some people flush ALDH2
Where your vitamin D, B12 and iron tend to sit
and more

Body & fitness →

Power or endurance: your muscle fiber type ACTN3
How your aerobic capacity responds to training
Strength and lean mass
Tendon and ligament strain under load COL5A1
Where your blood pressure tends to sit
and more

Health & longevity

Variants studied in people who live past 90
Telomere length, a marker of cell aging
Protective heart variants
Lp(a), the cholesterol particle diet barely moves
Background inflammation (CRP)
and more

Sleep & energy →

Morning lark or night owl
How late a coffee can be before it costs you sleep CYP1A2
Why caffeine makes some people jittery ADORA2A
How deep your sleep runs ADA
How much coffee you are drawn to drink
and more

Brain & mind

Warrior or worrier: how fast you clear dopamine COMT
The memory gene, and what the big studies found BDNF
Mood and emotional steadiness
Adventurous or cautious FOXP2
How fast you clear nicotine CYP2A6
and more

Your plans

Turn the findings into plans: connect your report to ChatGPT or Claude and ask for a week of meals, a training block or a morning routine built on your results.

03Get your VCF

How to download your VCF from Nebula Genomics, Dante Labs or Sequencing.com

Every provider lets you download your raw data for free; the VCF is the file to take. Steps checked against their own help pages in October 2026.

Ready inRight away, up to 48 hours if archived.vcf.gz

Nebula now sells as DNA Complete; the account and the download work the same way.

01
Sign in to your Nebula Genomics (DNA Complete) account.
02
Click “Download your data” in the top right corner.
03
If a file shows an “Unarchive” button, click it and wait for the email. This can take up to 48 hours.
04
Under the VCF file, click Download. The .tbi index, CRAM and FASTQ files are not needed.
05
Drop the .vcf.gz into the free analysis above as it is.

04Check your file

Will your file work?

Go by the file name. Whole genome sequencing data comes as .vcf or .vcf.gz; both work, whatever the size.

File ends in	What it is	Helisoma
`.vcf`	A plain-text VCF	Works
`.vcf.gz`	A compressed VCF, how most labs ship it	Worksno unpacking
`.zip`	An archive with a VCF inside	Works
`.g.vcf.gz`	A gVCF: every position, often several gigabytes	Workstakes longer
`.bam, .cram`	Aligned sequencing reads	Not a VCFask your lab for the VCF
`.fastq, .fq.gz`	Raw sequencing reads	Not a VCF
`.txt, .csv`	A chip export from 23andMe, AncestryDNA, MyHeritage or FamilyTreeDNA	Workson its own page

Not sure? Open the file in any text editor. If the first line starts with ##fileformat=VCF, it will work.

I

What's my ideal morning routine for maximum productivity?

Three findings in your report shape the answer:

chronotype · 15 markers your variants lean evening, consistently across all 15. A forced 6am routine works against that.
CYP1A2 caffeine clears slowly for you, and your ADORA2A version is the sensitive one. Moving the last coffee earlier is the cheapest thing to test.
FADS1 lower plant omega-3 conversion. Breakfast is the best window for salmon, sardines, or algae oil.

Try: wake by 9am, sunlight and water first, omega-rich breakfast, coffee at 10:30, deep work 11 to 2, second block 3 to 5pm.

06The file

What is inside your VCF raw data file

A VCF is plain text: a header, then one line per position. Six columns matter to you.

##

The header

Lines starting with ## name the format and the reference build, GRCh37 or GRCh38.

22 19963748

Chromosome and position

Where the marker sits, in that build’s coordinates.

rs4680

The ID

The marker’s public name. Sequencing labs often leave a dot here; Helisoma then finds the marker by its position instead.

G A

REF and ALT

The reference genome’s letter, then the alternative letter seen at this spot.

0/1

Your genotype

0 is the REF letter, 1 is the ALT letter. 0/1 is one of each: G and A.

./.

Not called

The test could not read this position for you. It never means “negative”.
