A short overview of publicly available software & tools developed within biomina or by biomina (affiliated) members:


speaq stands for "spectral alignment and quantitation" and constitutes a novel suite of informatics tools for the quantitative analysis of NMR metabolomic profile data. The core of the processing cascade is a novel peak alignment algorithm, called hierarchical Cluster-based Peak Alignment (CluPA). The algorithm aligns a target spectrum to the reference spectrum in a top-down fashion by building a hierarchical cluster tree from peak lists of reference and target spectra and then dividing the spectra into smaller segments based on the most distant clusters of the tree. To reduce the computational time to estimate the spectral misalignment, the method makes use of Fast Fourier Transformation (FFT) cross-correlation. Since the method returns a high-quality alignment, we can propose a simple methodology to study the variability of the NMR spectra.

CRPhos was originally developed as a tool to predict kinase-specific phosphorylation sites from a protein sequence. To this end, it employs a powerful algorithm based on a Conditional Random Fields model, which offers several advantages over alternative models. Due to its generic nature, the method was later extended to other post-translational modifications, such as SUMOylation, which it can predict with a significantly improved performance. Development of CRPhos is still ongoing.

VariantDB is a versatile annotation and filtering database with a web-based frontend, which automatically annotates variants with allele frequencies, functional impact, pathogenicity predictions and pathway information. VariantDB allows filtering under different inheritance models, including dominant, recessive or de novo inheritance. Furthermore, all available annotations can be set as additional filtering criteria. VariantDB is therefore a user-friendly and powerful tool to help in the interpretation of NGS data.
