SpaceCompare
Overview
SpaceCompare is a novel tool for comparing and analyzing ultra-large combinatorial chemical spaces. For the first time, users can compare trillion-sized chemical spaces using the combinatorial algorithmic approach of SpaceCompare.
The tool has three modes of operation
- overlap calculation of two combinatorial spaces
- distribution computation for five well-known physicochemical properties
- chemical space optimization by removal of fragments with undesired
Datasets
To use SpaceCompare on an existing chemical space, you can access the Knowledge Space in its topological fragment space representation at https://www.zbh.uni-hamburg.de/forschung/amd/datasets/knowledgespace.html.
Software Availability
SpaceCompare is freely available for non-commercial and academic users for Linux, macOS, and Windows as part of our NAOMI ChemBio Suite. To download SpaceCompare, register at https://software.zbh.uni-hamburg.de. Non-academic users can get an evaluation license free of charge. Only minimal setup steps are required to run SpaceCompare. All feedback (software.zbh(at)uni-hamburg.de) is highly appreciated.
