Two files.
Evidence to examine.
Compare compatible RAW genotype files, adjust segment thresholds and inspect the evidence in a chromosome browser and segment table.
Current price, availability, device requirements and license terms are shown in Microsoft Store. No website purchase is required to view the listing.
Inspect the evidence behind the summary.
A compact estimate is a starting point. Return to the chromosome, interval, thresholds and available markers before drawing conclusions.
- Chromosome browser
- Review candidate shared segments across the autosomes, alongside the analysis type and selected thresholds.
- Segment table
- Inspect chromosome, start and end position, cM length, SNP count and the reported segment type.
- IBD1, IBD2 and HBD options
- Review supported interpretations of one-copy sharing, two-copy sharing and homozygous regions. These labels depend on the method and input evidence.
- Kinship and degree estimates
- Use the summary to frame a research question. Estimated relationship classes do not verify a family tree or identify a particular relationship on their own.
- Clipboard and TSV export
- Move evidence into a spreadsheet or another suitable workflow. Protect exported genetic information and share only what you intend to disclose.
Load. Compare. Examine.
Keep original copies and choose inputs with suitable structure and marker overlap.
Load the two files
Choose compatible genotype exports for the two people whose data you are authorized to compare. Review their format and available records.
Choose the thresholds
Set minimum cM and SNP thresholds and the supported comparison options. Keep these settings with your interpretation.
Review and export
Examine the chromosome browser and segment table. Copy or export the evidence you need for independent follow-up.
Get the Windows app through its store.
The existing Microsoft Store listing provides current pricing and installation requirements for your region and device.
- Pricing and licensing
- Use the terms displayed by Microsoft Store. A website PRO purchase should not be assumed to unlock this separate application.
- System requirements
- Check the listing's current Windows and hardware requirements before purchasing or installing.
- Responsible use
- Core comparison runs in the Windows application. Retain originals and protect files and exports. The output is for research, not clinical, legal or identity decisions.
Practical questions.
Understand the file type, the access route and the limits of an estimate.
Where do I get the application?
Use the existing Microsoft Store listing or open it in the Microsoft Store app. Check the current regional price, device requirements, availability and license terms there. This page does not sell a website entitlement for the application.
What do I compare?
Load two compatible RAW genotype files, rather than two shared-match segment lists. Supported input structures and usable marker overlap affect the comparison. Check compatibility before interpreting the output.
What do cM and SNP thresholds change?
They filter the candidate segments reported by the comparison. Raising or lowering a threshold changes which evidence is retained. Threshold choices, marker overlap and file quality should stay visible when interpreting a result.
Do IBD, HBD or relationship labels prove a family relationship?
No. These are model-based segment and kinship interpretations. Review the input quality, shared-segment evidence and independent genealogical information. A relationship estimate is not proof of identity, a verified family connection or a clinical diagnosis.
Can I export the results?
The application provides clipboard copying and TSV export alongside the chromosome and segment-table views. Exports contain genetic information; consider their recipients and storage.
Is this DNA Segment Studio?
No. DNA Segment Comparator compares compatible RAW genotype files. The separate DNA Segment Studio legacy beta uses two existing shared-segment tables with a common match to investigate inferred segments.
Where does comparison run?
The core comparison runs in the Windows application on your computer. Software acquisition through Microsoft Store and linked online services have their own requirements and terms. Keep original inputs and exported genetic information protected.
