PMID: 29425024
DOI: 10.1021/acs.analchem.7b04073

[…] chromatography (ultimate 3000, dionex, sunnyvale, ca) and fourier transform mass spectrometry (q-exactive, thermo scientific, waltham, ma). data was extracted using aplcms with modifications by xmsanalyzer. see si for details. the metabolomics data set is available upon request to the corresponding authors., statistical analysis, network/pathway analysis, and metabolite set enrichment […]

[…] of ions that are trapped and oscillate in a chamber. the computational aspects of metabolomics are also in rapid progress, including open source feature extraction tools (xcms , openms , aplcms , xmsanalyzer ), databases of metabolites (human metabolome database , , metlin , pubchem , chebi ), and data analysis tools (xcms online , metaboanalyst , mummichog ). it should be noted […]

[…] metabolomics data analysis. feature and sample quality assessment was performed based on coefficient of variation (cv) and pearson correlation, respectively, based on the technical replicates using xmsanalyzer (). metabolites with cv >50% in our samples were excluded from further analyses. potential metabolite identities were determined by performing an online search (10 ppm mass accuracy) […]

[…] gradient used in this study cannot resolve structural isomers and isobaric species []. peak detection, noise removal, and alignment was performed using aplcms v6.0.1[] and xcms v1.44[] with xmsanalyzer v2.0.4[], yielding a data table with accurate mass (m/z), retention time and intensity for each m/z feature across all samples. an m/z feature is defined as the unique combination of m/z, […]

[…] to be user friendly by providing a file-based operation and a wrapper function for a single command line batch process of lc-ms data, but still requires some computational knowledge to operate. xmsanalyzer [] is an r package for improving feature detection that integrates with existing packages such as aplcms and xcms. it systematically re-extracts features with multiple parameter settings […]

[…] using anion exchange and c18 chromatography combined with the thermo orbitrap-velos (thermo fisher, san diego, ca) mass spectrometer using an m/z range of 85 to 850. the data was pre-processed using xmsanalyzer in combination with aplcms. for each feature, there were three readings per subject. an average metabolite intensity value was calculated from the non-zero readings for each individual.
