5 Conserved Sequence Tags (CST)



8 Genome browser

9 KinWeb

11 Three genes a) b) Ig-IIg-IIIg-IIITMTyr Kinase // CSTs Ser-Thr Kinase CST // Ser-Thr Kinase c) // acb CST IIIIII

12 Selection of homologous chromosome regions from human and mouse genomes. Comparison of selected regions using BLASTZ, a program based on a local similarity algorhitm. Further analysis on the dataset looking for subpopulations sharing specific characteristics, using different programs, such as: - Blast of CSTs vs EST, human and other species genomes - Program for calculation of CPS score (Coding Potential Score) - RNA structure prediction programs Selection of the definitive set of CSTs based on specified thresholds (identity >= 70%; length >= 100 bp) using StrongHits. Insertion of selected CSTs into DB and extensively annotation for: - type (i.e. intergenic, exonic etc.) according to Ensembl - Coding capability according to Ensembl - Distances from other genes and coding regions - Calculation of Log Score according to UCSC comparison of human and mouse genomes Masking sequences of repetitive elements to reduce the noise fatally introduced by repeated sequences through RepeatMasker.

39 ClusterCluster Cluster Nodes Access Server Access Server Access Server A tool can require the execution of multiple, simultaneous processes Distributed execution of parallel requests

40 -PHP internal routines (basic drawing, processing) -ImageMagick (more advanced processing) -Image converters -Special tools (PDL, deconvolution) -Tools developed in-house (cell tracking) -...... What software may be linked

41 -Convenient graphic interface -Access to a vast library of image processing steps -No specific interface requirements -Remote processing on parallel hardware -Support for a large number of concurrent users -System independent (works on Mac, PC, Linux etc.) -No need to install. A browser is enough. Advantages
