Experiment Experiment (in-silico)- a process that combines
together data with a set of activities (programs, services) that act on that data in order to produce experiment results Experiment plan – a specific type of software Experiment run – a specific execution of the experiment
Complex workflow going beyond manual simple and repeatable execution of installed programs
Combines steps realized on a range of software environments, platforms, tools, languages etc.
Developed, shared and reused collaboratively amongst ad-hoc researching teams
Composed of collaboratively owned libraries and services used (called gems) and experiment parts (called snippets)
Virtual Laboratory – environment for development, execution and sharing of experiments

Binding sites in proteins Comparison of Services for Predicting
Ligand Binding Sites Multiple services available on the Web Conversions between data formats Visualization scripts (Jmol, Gnuplot) Single access based on experiments
developed in Virtual Laboratory Calculation of hydrophobicity profiles
Multiple scales, parameters, input data Computed using PL-Grid resources –
easy access to Zeus cluster at Cyfronet Management of experiment results:
~ 1 Million output files Using semantic integration framework
for metadata management

Analysis of water solutions of aminoacids Involving multiple steps realized with many
tools, langauges and libraries used for Packmol – molecular dynamics simulations
of packing molecules in a defined regions of space
Jmol – visualization of solution Gaussian – computing a spectrum of the
solution Python/CCLIB – extracting spectrum info jqPlot – displaying plot
Collaboration with computational chemists of ACC Cyfronet AGH and Departament of Chemistry, Jagiellonian University, Dr. Mariusz Sterzel, Klemens Noga

ConclusionsComplex scientific applications need
dedicated tools and approaches.In-silico experiments are supported by Virtual
Laboratory powered by GridSpace2 technology.
Applications:BioinformaticsComputational chemistryMore are welcome!
Virtual laboratory is open for PL-Grid users.
