Summary
This study updates selscan software to analyze genomic positive selection using unphased genetic data. The new methods allow for accurate selection identification without requiring haplotype phase information.
Area of Science:
- Genomics
- Population Genetics
- Bioinformatics
Background:
- Haplotype-based statistics are crucial for detecting positive selection in genomes.
- Existing methods often require accurate haplotype phase information, which can be difficult to obtain.
Purpose of the Study:
- To provide an updated version of the selscan software.
- To implement haplotype-based statistics for use with unphased genetic data.
Main Methods:
- The study re-defines existing haplotype-based statistics.
- These redefined statistics are implemented in the updated selscan software for unphased data analysis.
Main Results:
- The updated selscan software can now analyze positive selection using unphased genetic data.
- This overcomes the limitation of requiring haplotype phase information for popular statistical methods.
Conclusions:
- The updated selscan provides a valuable tool for population geneticists.
- It facilitates the identification of recent or ongoing positive selection in genomic datasets without the need for phasing.

4.2K
A scanning electron microscope (SEM) is used to study the surface features of a sample by using an electron beam that scans the sample surface in a two-dimensional manner. Typically, areas between ~1 centimeter to 5 micrometers in width can be imaged. SEM can be used to image bacteria, viruses, tissues as well as larger samples like insects. Conventional SEM gives a magnification ranging from 20X to 30,000X and spatial resolution of 50 to 100 nanometers.

01:192D NMR: Heteronuclear Single-Quantum Correlation Spectroscopy (HSQC)
719
Heteronuclear single-quantum correlation spectroscopy (HSQC) is a 2D NMR technique that reveals one-bond correlations between hydrogen and a heteronucleus. The HSQC experiment is similar to the heteronuclear correlation experiment (HETCOR) but is more sensitive. In the HSQC spectrum, the proton chemical shift is plotted on the horizontal F2 axis, while the 13C chemical shift is plotted on the vertical F1 axis. The corresponding proton and 13C spectra are also shown. The HSQC contour plot does...
