Data analysis tools

Bioinformatics is an essential part of the high throughput operations. On the one hand, all experimental data need to be aggregated, organised, statistically evaluated, and visualized. On the other hand, bioinformatic tools can be used to explore the vast drug response data accumulated over the years to generate new knowledge and formulate new hypotheses.

Bioinformaticians and computer scientists at FIMM use various programming instruments (R, Python, etc.) to process the experimental data. Several computational tools have been built in house to facilitate data processing.

Dr. Tero Aittokallio's group developed a "Drug Sensitivity Score" (DSS) - a single number describing cellular response to a particular drug, making it possible to compare responses of different cells to different drugs between each other (1).

open access tool has been built for automated analysis of drug sensitivity and resistance (DSRT) data (2).

Several computationsl pipelines ( (3,4), (5)) have been developed to explore potential synergy between drugs and identify useful drug combinations for particular molecular targets (3).

Dr. Imre Västrik developed an in-house data analysis platform for processing Individualised Systems Medicine clinical samples and combining DSRT results and patient mutations, thus greatly facilitating the communications between researchers and clinicians.
