VCF Explorer

he decreasing cost high-throughput technologies led to a number of sequencing projects consisting thousands of whole genomes. The paradigm shift from exome to whole genome brings a significant increase in the size of output files. Most of the existing tools which are developed to analyze exome files are not adequate for large VCF files produced by whole genome studies. In this work we present VCF-Explorer, a variant analysis software capable of handling large files. Efficient memory management of the program and the elimination of preliminary parsing step enable to carry out the analysis at ordinary computers. VCF-Explorer presents an easy to use environment where various types of queries for the annotation and the samples can be defined. VCF-Explorer can be run at different environments and computational platforms ranging from a standard laptop to an advanced server.

Today’s small-to-medium-sized (SMB) businesses and large enterprises are saving on their monthly communications costs by making one simple decision: to switch to a VoIP service solution from their old, outdated Plain Old Telephone Service (POTS). By choosing a new VoIP service, these companies enjoy the flexibility, reliability, call features, and audio quality that only a VoIP service can provide. Plus, they cut their phone bill by up to 70%!
