LASER server: ancestry tracing with genotypes or sequence reads.


ABSTRACT: 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.The LASER server is freely accessible at http://laser.sph.umich.edu/.dtaliun@umich.edu or wangcl@gis.a-star.edu.sg.Supplementary data are available at Bioinformatics online.
