The full dataset also features retention times, m/z values and identity of structurally resolved metabolites for further investigation.
The chromatograms of adducts that differ only by the isotope content in the adducted HNE (d0 or d4) had similar features (retention times of peaks).
The raw MS data (wiff.scan files) were converted to mzXML files using ProteoWizard MSConvert and processed using XCMS for feature detection, retention time correction and alignment.
For the feature phyletic retention (PR), the number of prokaryotes having orthologs of the knocked out gene showed a positive correlation to essentiality (P = 2.1E-16) supportheg the findings of a previous study that conserved genes in evolution hint for their essentiality [ 14].
They proposed a decision tree-based prediction of the most frequent substructures, based on mass spectral features and retention index information, for classification of unknown metabolites into different compound classes.
Moreover, in the light of the porosity features, gas retention and viscous flow is revealed to play key roles in the formation of the inner structure of Cf/SiCm.
In summary, integrated primary ion chromatographic peaks from all the samples are binned based on chromatographic features of retention index and ion mass, well correlated bins within the retention index window are grouped to create a library entry to represent a chemical entity.
PHA2 features sodium retention, hyperkalemia, mild hyperchloremic metabolic acidosis, and hypertension.
Non-annotated mass/charge (m/z) features, column retention time, and ion intensity were collected as data.
