Abstract

: We present ChAsE, a cross-platform desktop application developed for interactive visualization, exploration and clustering of epigenomic data such as ChIP-seq experiments. ChAsE is designed and developed in close collaboration with several groups of biologists and bioinformaticians with a focus on usability and interactivity. Data can be analyzed through k-means clustering, specifying presence or absence of signal in epigenetic data and performing set operations between clusters. Results can be explored in an interactive heat map and profile plot interface and exported for downstream analysis or as high quality figures suitable for publications. AVAILABILITY AND IMPLEMENTATION: Software, source code (MIT License), data and video tutorials available at http://chase.cs.univie.ac.at CONTACT: : mkarimi@brc.ubc.ca or torsten.moeller@univie.ac.atSupplementary information: Supplementary data are available at Bioinformatics online.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • K-means clustering (K=5) on HNF4A and FOXA2 bound regions identified 5 clusters, with large overlap between HBRs and FBRs (Cl2, Cl3, Cl4) and two clusters showing exclusive binding of either HNF4A or FOXA2 (Cl1 and Cl5).

    “To address this, we performed K-means clustering (K=5) on HNF4A and FOXA2 bound regions in hepatocytes using ChAsE (35) and identified 5 clusters. As expected, a large overlap was observed between HBRs and FBRs (Cl2, Cl3 and Cl4), however, two clusters showed exclusive binding of either HNF4A or FOXA2 (Cl1 and Cl5, respectively) (Fig. 2A).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
