"We are pleased to announce DNA.Land Compass!
http://compass.dna.land

This is an experimental website that enables users to explore and investigate their imputed VCF files. DNA.Land users can download their VCF file, then visit http://compass.dna.land and search for genotypes.

The website is designed to be simple and secure - it does not require installing any software, and your VCF/genotype never leaves your computer.

Please note: You must download your .TBI file to use DNA.Land Compass! This is a new file that we have just begun offering today.
Have a go and let us know what you think!

Comments, feedback, and suggestions are very welcome at: compass@dna.land

I played with a it a bit but I don't have not much experience with tools like this.

For some reason it wont process my data. Cool concept nonetheless!

needs both files (VCF and .TBI files)mine were both listed in files on DNAland (my user page)

but if you have a problem they want to know about it.(Others have had some issues)
they have to be done at the same time I found the instructions in FAQ(shift and highlight)
it worked for me

I'll play with it later this evening

can't upload the files as they want me to.

fixed: make sure you get the proper vcf.gz and vcf.gz.tbi extensions as Windows can change those on you. for instance, it turned my vcf file into a vcard format, not good.

as anglesquvile talled me :
here is what dna land say about the proces of imputation nothing is 100%

How accurate is the imputed VCF from DNA.Land?
DNA.Land is fairly accurate, but not 100%, since imputation—the process by which we estimate the missing information in your genotype—cannot be done with 100% certainty.That being said, in internal testing, our imputation algorithms correctly imputed about 99.994% of SNPs. However, since this is a stochastic, probabilistic analysis, there is always the possibility that we are displaying an incorrect genotyoe. Never use the information provided on this website as-is; always consult a certified clinician before making any medical decision.

I had the same problem, I had to rename the xxxx.vcf to .xxxx.vcf.gz
at least for me that worked.

ok, something is working, but now what? any sort of guide for Dummies would be useful.
