LASER server: ancestry tracing with genotypes or sequence reads.

Summary: To enable direct comparison of ancestry background in different studies, we developed LASER to estimate individual ancestry by placing either sezquenced or genotyped samples in a common ancestry space, regardless of the sequencing strategy or genotyping array used to characterize each sample. Here we describe the LASER server to facilitate application of the method to a wide range of genetic studies. The server provides genetic ancestry estimation for different geographic regions and user-friendly interactive visualization of the results.

Availability and Implementation: The LASER server is freely accessible at https://laser.sph.umich.edu/.
