Ideograms: The Art of Drawing Chromosomes

September 18th, 2009 | Posted in Bioinformatics

Ideograms are graphical representations of the genome. Along with appeasing the need to visualize the less lively genotype data that is obtained from microarrays, ideograms can actually help in the analysis of data. Methods for creating ideograms along with sample ideograms are discussed.

Phasing: Determining Which SNPs are Inherited Together

September 8th, 2009 | Posted in Analyze Your Own SNPs, Bioinformatics

Biallelic DNA microarray data SNPs, can be made much more useful if it haplotype information is also available. However, the process of phasing biallelic data is not so simple.
