By analyzing and understanding these differences, researchers hope to identify cancer biomarkers. Due to the size and complexity of the data produced, however, analysis can still be very slow and time consuming. This is further complicated by the fact that datasets obtained will exhibit incidental differences in intensity and retention time, not related to actual chemical differences in the samples being evaluated. Additionally, automated tools to correct these errors do not always produce reliable results. This work presents a new analytics system that enables interactive comparative visualization and analytics of metabolomics data obtained by two-dimensional gas chromatography-mass spectrometry (GC \u00d7 GC-MS). The key features of this system are the ability to produce visualizations of multiple GC \u00d7 GC-MS data sets, and to explore those data sets interactively, allowing a user to discover differences and features in real time. The system provides statistical support in the form of difference, standard deviation, and kernel density estimation calculations to aid users in identifying meaningful differences between samples. These are combined with novel transfer functions and multiform, linked visualizations in order to provide researchers with a powerful new tool for GC \u00d7 GC-MS exploration and bio-marker discovery.<\/jats:p>","DOI":"10.1186\/1471-2105-13-s8-s6","type":"journal-article","created":{"date-parts":[[2019,12,11]],"date-time":"2019-12-11T02:00:28Z","timestamp":1576029628000},"update-policy":"http:\/\/dx.doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["OmicsVis: an interactive tool for visually analyzing metabolomics data"],"prefix":"10.1186","volume":"13","author":[{"given":"Philip","family":"Livengood","sequence":"first","affiliation":[]},{"given":"Ross","family":"Maciejewski","sequence":"additional","affiliation":[]},{"given":"Wei","family":"Chen","sequence":"additional","affiliation":[]},{"given":"David S","family":"Ebert","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2012,5,18]]},"reference":[{"issue":"2","key":"5177_CR1","doi-asserted-by":"publisher","first-page":"107","DOI":"10.1016\/j.chemolab.2003.12.009","volume":"71","author":"SE Reichenbach","year":"2004","unstructured":"Reichenbach SE, Ni M, Kottapalli V, Visvanathan A: Information technologies for comprehensive two-dimensional gas chromatography.
