GeneViz, GeneFocus


Contentsoft of Munich has released version 1.1 of GeneViz, its gene expression bioinformatics software, and is now granting free academic licenses to qualifying non-commercial research groups. The software includes two data analysis methods: double conjugated clustering, a two-way agglomerative clustering method that finds submatrices of tightly clustered samples and detects “noisy” genes that do not help distinguish the cluster; and SVD sorting, which orders genes using a left singular vector, and orders samples according to a right singular vector, the company said.

Commercial users can download the software free for 15 days. The software and other information is available at http://www.contentsoft. de/download.php.

Sunergia Group of Reston, Va., has introduced the GeneFocus genetic microarray scanners and analysis software to the US market. The scanners include the DNAscope LM, IV, and V, and the Open Frame DNAscope. All of the scanners come with the MacroView microarray analysis software. The DNAscope LM, IV, and V all image the area of a microscope slide with 5 micron pixels. The DNAscope LM and IV collect Cy3 and Cy5 images in sequence, while the DNAscope V collects both images simultaneously. The Open Frame Research DNAscope is designed for the high-end market in non-standard microarrays and liquid biochips, the company said.

The company’s MacroView analysis software performs automated spot and grid detection, spot integration, local background subtraction, and automated grid alignment. It accepts images from microarray scanners that use 16-bit TIFF files and runs on Windows 95, 98, NT 4.0 and Windows 2000.
