Instrument Name: | Thermo Q Exactive Plus Orbitrap |
Instrument Type: | Orbitrap |
MS Type: | ESI |
MS Comments: | Data from each mode were independently analyzed using Progenesis QI software (v2.3) (Nonlinear Dynamics, Durham, NC). Metabolic features from blanks and those that did not show sufficient linearity upon dilution in QC samples (r<0.6) were discarded. Only metabolic features present in >2/3 of the samples were kept for further analysis. Missing values were imputed by drawing from a random distribution of low values in the corresponding sample. Intensity drift was corrected using SERRF. Data quality post-normalization was verified by ensuring clustering of pooled sample replicates on a principal component analysis (PCA) plot. |

Instrument Name: | ABI Sciex 5500 QTrap |
Instrument Type: | Triple quadrupole |
MS Type: | ESI |
MS Comments: | Lipidyzer data were reported by the Lipidomics Workflow Manager (LWM, v1.0.5.0) software which calculates concentrations for each detected lipid as average intensity of the analyte MRM relative to the average intensity of the most structurally similar internal standard (IS) MRM multiplied by its concentration. Lipids detected in less than 2/3 of the samples were discarded and missing values were imputed by drawing from a random distribution of low values class-wise in the corresponding sample. Data quality was verified by ensuring clustering of the quality control replicates analyzed on a PCA plot. We detected lipid species belonging to 13 classes (e.g. CE, CER, DAG, FFA, HCER, LCER, DCER, LPE, LPC, PC, PE, SM, TAG) and their abundance were reported as concentrations in nmol/g. The Q1 and Q3 mass provided in the metadata were used to target specific lipid classes. Lipids with the designated Q1 mass, also known as the parent ion, are selected from the first quadrupole. The lipids are then fragmented and sent to the third quadrupole. In the third quadrupole, the desired lipid class is selected based on its Q3 mass. |
