    Visualization of Protein-Ligand Graphs

    Visualization of Protein-Ligand Graphs

    Compute protein graphs. Moved to https://github.com/MolBIFFM/PTGLtools

    NOTE: Project moved to https://github.com/MolBIFFM/PTGLtools. The Visualization of Protein-Ligand Graphs (VPLG) software package computes and visualizes protein graphs. It works on the super-secondary structure level and uses the atom coordinates from PDB files and the SSE assignments of the DSSP algorithm. VPLG is command line software. If you do not like typing commands, try our PTGL web server: http://ptgl.uni-frankfurt.de/

    TAG

    A tool for metatranscriptome assembly using metagenome graph

    TAG is a tool for metatranscriptome assembly using de Bruijn graph of matched metagenome as the reference. TAG is an application of a reads mapping algorithm that we developed for mapping of short reads onto a de Bruijn graph of assemblies. A hash table of junction k-mers (k-mers spanning branching structures in the de Bruijn graph) is used to facilitate fast mapping of reads to the graph. We have shown that TAG helps to assemble substantially more transcripts from metatranscriptomic...

    RT-alignment

    Graph-based time alignment algorithms for multiple LC-MS datasets

    ... changes under different conditions. The main challenge in this task lies in correcting retention time shifts, which are inevitable even on the same instrument and under the same elution conditions. For large-scale studies, multiple instruments or multi-week experiments are often required, which exacerbates the problem. We present a new graph-based time alignment algorithm that can align these less similar LC-MS maps, which cannot be effectively handled by existing methods.

    SplitMEM

    Graphical pan-genome analysis with suffix skips

    With the rise of improved sequencing technologies, genomics is expanding from a single reference per species paradigm into a more comprehensive pan-genome approach with multiple individuals represented and analyzed together. Here we introduce a novel O(n log n) time and space algorithm called splitMEM, that directly constructs the compressed de Bruijn graph for a pan-genome of total length n. To achieve this time complexity, we augment the suffix tree with suffix skips, a new construct...

    MolSig

    The Stereo Signature Molecular Descriptor

    An algorithm to compute molecular graph descriptors considering the stereochemistry of the molecular structure, based on our previously introduced signature molecular descriptor. The algorithm can generate two types of descriptors, one which is compliant with the Cahn-Ingold-Prelog priority rules, and a faster one based on our previous definition of a directed acyclic graph that isaugmented to a chiral molecular graph.

    Mix

    Mix is a tool to combine multiple assemblies from NGS data.

    Mix is a tool that combines two or more draft assemblies, without relying on a reference genome and has the goal to reduce contig fragmentation and thus speed-up genome finishing. The proposed algorithm builds an extension graph where vertices represent extremities of contigs and edges represent existing alignments between these extremities. These alignment edges are used for contig extension. The resulting output assembly corresponds to a path in the extension graph that maximizes...
