Microbial source-tracking is a useful tool for trace evidence analysis in Forensics.Community-wide massively parallel sequencing profiles can bypass the need for satellite microbes or marker KIDS ELDERBERRY COUGH SYRUP sets, which are unreliable when handling unstable samples.We propose a novel method utilizing Aitchison distance to select important suspects/sources, and then integrate it with existing algorithms in source tracking to estimate the proportions of microbial sample coming from important suspects/sources.A series of comprehensive simulation studies show that the proposed method is capable of accurate selection and therefore improves the performance of current methods such as Bayesian SourceTracker washer and FEAST in the presence of noise microbial sources.
