PMID: 28938074
DOI: 10.1021/acs.analchem.7b01581

[…] as two separate spectra, one at higher energy in the collision cell for fragments from sites 6–79, and one at lower energy for fragments from sites 114–130. data analysis was performed with xtract (thermo scientific) or mmass software, and graphical fragment maps were created with prosight lite. all intensity values used for the determination of weighted-average charges were normalized […]

[…] meaning that cross-link analysis is not routinely possible. maxquant was recently adopted for quantifying cross-links being a first exception here. also, walzthoeni et al. developed software xtract to be used in conjunction with their identification pipeline for automated quantitation of cross-linking data . previously performed proof-of-principle work relied on an elementary […]

[…] “sweet heart for hcd” approach could succeed., c* corresponds to carbamidomethyl cys; cys(o) indicates the oxidation of alkyl cys. the first column represents automated deconvolution values using xtract, a feature of thermo’s xcalibur software. the correct value determined for the man6 and man7 dimer indicates that it can compensate for the missing monoisotopic peak., assumed formylation […]

[…] as described (). peptides were fractionated by multidimensional chromatography followed by tandem mass spectrometric analysis on a ltq-orbitrap mass spectrometer (thermo fisher scientific). raw-xtract (version 1.8) was used to extract peak list information from xcalibur-generated raw files. database searching of the ms/ms spectra was performed by using the prolucid algorithm (version 1.0). […]

[…] (80, 100, 150, and/or 180 v) of hcd. all precursor and fragment ions were acquired using a mass resolution of 60,000 with an average of 3 microscans and a signal-to-noise threshold of 3. the xtract algorithm from xcalibur 3.0 software (thermo fisher scientific) was used to determine the decharged masses of the observed ions, which were then inserted into prosight lite […]

[…] were inspected with the xcalibur qual browser (thermo xcalibur 2.2 sp1.48, thermo fisher scientific, waltham, ma, usa) and deconvolution of isotopically resolved spectra was carried out by using the xtract algorithm of xcalibur qual browser. the protein assignment was done by comparison to the retention time of the hplc run and corresponding lc-ms/ms information from sds-page trypsin digests., […]

[…] the supporting information., for tandem spectra of sp, fragments were manually analyzed for b, c, y, and z ion types. for intact protein analyses, extracted mass spectra were deconvoluted using auto xtract in protein deconvolution 4.0 (thermo fisher scientific, bremen, germany). deconvolution settings were s/n threshold: 1, fit factor: 80%, and remainder threshold: 25%. deconvoluted results […]
