This is the archive site for PRICE (Paired-Read Iterative Contig Extension), a de novo genome assembler implemented in C++ by Graham Ruby. This tool is no longer maintained, and many other tools are now superior to it. It is still here for download if you want to give it a try! Its name describes the strategy that it implements for genome assembly: PRICE uses paired-read information to iteratively increase the size of pre-assembled contigs. It was designed to address the challenge of assembling viral genomes that constituted a small minority of the reads within ultra-deep, short-read, metagenomic, shotgun datasets.

HMMSplicer discovers splice sites in high throughput sequencing datasets without using gene models. HMMSplicer can also be used to find non-canonical junctions as well. HMMSplicer was benchmarked on publickly available A. thaliana, H. sapiens, and P. falciparum datasets and performs well on all genomes. Information about the datasets tested, including the exact command parameters and the final results, is provided. HMMSplicer is implemented in Python and is freely available for all.

decorative iconVersaCount is a simple application to assist with the counting of cells by microscopy. When used with a numeric keypad, it can significantly increase counting efficiency when compared with a traditional clicker. Although it was designed for malaria work, it can be customized for a wide variety of cell counting applications. VersaCount was written by Charlie Kim.

decorative iconExpressionNet is a program written by Jingchun Zhu that uses Bayesian network learning algorithms to explore relationships among random variables to generate network models. The software has been used to study the transcriptional response to environmental perturbations in budding yeast. Details of the program and the study of yeast transcription using Bayesian Networks was published in PLoS ONE.

ArrayOligoSelector (AOS) is an open source program developed by Jingchun Zhu for the purpose of systematically designing gene-specific long oligonucleotide probes for entire genomes. For each open reading frame, the program optimizes oligo selection based upon several parameters, including uniqueness, complexity, secondary structure, GC content, and 3' end proximity.
AOS also is hosted at SourceForge. This site contains documentation and a user-friendly how-to.
For more information, download an excerpt from Jing's thesis describing the AOS algorithm and implementation here.

ArrayMaker 2 provides high performance robotic control of microarrayer robots with an incredibly intuitive, easy to use interface. ArrayMaker 2 is optimized for use with the new generation of ultra fast linear servo driven arrayers, yet it is backwards compatible with the original MGuide style of ball-screw driven arrayers.
