The rtcutoff in function getpaired could be used to set the cutoff of the distances in retention time hierarchical clustering analysis. Retention time cluster cutoff should fit the peak picking algorithm. For HPLC, 10 is suggested and 5 could be used for UPLC.
Web12 de abr. de 2024 · An appropriate size of this RMSD cutoff was defined for each fuzzy cluster individually by computing the mean value of the largest 20% of the RMSD values between the centroid and cluster members of the cluster identified in the current iteration (it is equal to 5.5 Å for the cluster shown here). WebFeatures were aligned to their respective MS/MS spectra, then product ions were dynamically binned and resulting spectra were hierarchically clustered and grouped based on a cutoff distance threshold. Using the simplified visualization and the interrogation of cluster ion tables the number of lucibufagins was expanded from 17 to a total of 29.
