Again we start with either the envelopes or the differentials of the envelopes of the six frequency bands but omit the step of peak picking.
This XIC is composed of a set of noise without any chromatographic peak and, therefore, is eliminated during the step of chromatographic peak fitting.
Briefly, the procedure consists of four steps: (1) normalization of peak fragment lengths, (2) peak alignment, (3) normalization of peak heights, and (4) identification of differentially expressed TDFs.
We accomplished the first step of identifying peaks in the frequency histogram by applying a novel random data-shuffling method (see Supplementary Material for details).
With those extra steps in place for times of peak demand, the capacity margin rises to 5.1%, the assessment shows.
Furthermore, both sets of peaks show a broadening after the second deformation step.
For a parent peptide with mass m and charge q, the precursor and cluster ion peaks to be removed from the spectrum are those having their mass/charge peaks within 0.05 Da of [ m + (q i - 1 + k) × Hyd]/ q i for every q i = 1,..., q, and k = 0, 1,..., q i - 1. Peak centroidizing is the second step of RAId_DbS's peak processing.
The appearance of the above peaks indicated multi-step phase transitions, and the location of peak voltages was consistent with the previously reported ones [2]. Figure 4b showed the galvanostatic discharge/charge curve for the first cycle at the specific current of 30 mA g−1.

Filtering out such pseudobinding sites is only possible by comparing the ChIP sample with an input sample, and this step is essential for the specificity of peak calling (Rozowsky et al. 2009).
