HeatMap
This heatmap provides an overview of the performance of the quantms DIA (DIA-NN) results.
This plot shows the pipeline performance overview. Some metrics are calculated.
*Heatmap score[Contaminants]: as fraction of summed intensity with 0 = sample full of contaminants;
1 = no contaminants
*Heatmap score[Pep Intensity (>23.0)]: Linear scale of the median intensity reaching the threshold,
i.e. reaching 2^21 of 2^23 gives score 0.25.
*Heatmap score[Charge]: Deviation of the charge 2 proportion from a representative
Raw file (median). For typtic digests, peptides of charge 2 (one N-terminal and one at
tryptic C-terminal R or K residue) should be dominant. Ionization issues (voltage?),
in-source fragmentation, missed cleavages and buffer irregularities can cause a shift
(see Bittremieux 2017, DOI: 10.1002/mas.21544)
*Heatmap score[RT Alignment]: Compute 1 minus the mean absolute difference between 'RT' and 'Predicted.RT',
and take the maximum of this value and 0. 1: |RT - Predicted.RT| = 0
*Heatmap score [ID rate over RT]: Judge column occupancy over retention time.
Ideally, the LC gradient is chosen such that the number of identifications
(here, after FDR filtering) is uniform over time, to ensure consistent instrument duty cycles.
Sharp peaks and uneven distribution of identifications over time indicate potential for LC gradient
optimization.Scored using 'Uniform' scoring function. i.e. constant receives good score, extreme shapes are bad
*Heatmap score [Norm Factor]: Computes the mean absolute deviation (MAD) of 'Normalisation.Factor' from its mean.
0 = high variability in normalization factors; 1 = perfectly consistent normalization factors
*Heatmap score [Peak Width]: Average peak width (RT.Stop - RT.Start). 1 = peak width equals 0;
0 = peak width equals 1 or greater

Identification Summary
Number of Peptides identified Per Protein
This plot shows the number of peptides per protein in quantms pipeline final result
This statistic is extracted from the out_msstats file. Proteins supported by more peptide
identifications can constitute more confident results.
ProteinGroups Count
Number of protein groups per raw file.
Based on statistics calculated from mzTab, mzIdentML (mzid), DIA-NN report files, or FragPipe psm.tsv.
Peptide ID Count
Number of unique (i.e. not counted twice) peptide sequences including modifications per Raw file.
Based on statistics calculated from mzTab, mzIdentML (mzid), DIA-NN report files, or FragPipe psm.tsv.
Modifications
Compute an occurrence table of modifications (e.g. Oxidation (M)) for all peptides, including the unmodified (but without contaminants).
Post-translational modifications contained within the identified peptide sequence.
1. _M(Oxidation (M))LVLDEADEM(Oxidation (M))LNK_
2. _(Acetyl (Protein N-term))M(Oxidation (M))YGLLLENLSEYIK_
3. DPFIANGER
* 33% of 'Oxidation (M)'
* 33% of '2 Oxidation (M)'
* 33% of 'Unmodified'
The plot will show percentages, i.e. is normalized by the total number of peptide sequences (where different charge state counts as a separate peptide) per Raw file. The sum of frequencies may exceed 100% per Raw file, since a peptide can have multiple modifications.
E.g. given three peptides in a single Raw file1. _M(Oxidation (M))LVLDEADEM(Oxidation (M))LNK_
2. _(Acetyl (Protein N-term))M(Oxidation (M))YGLLLENLSEYIK_
3. DPFIANGER
, the following frequencies arise:
* 33% of 'Acetyl (Protein N-term)'* 33% of 'Oxidation (M)'
* 33% of '2 Oxidation (M)'
* 33% of 'Unmodified'
Thus, 33% of sequences are unmodified, implying 66% are modified at least once. If a modification, e.g. Oxidation(M), occurs multiple times in a single peptide it's listed as a separate modification (e.g. '2 Oxidation (M)' for double oxidation of a single peptide).
FragPipe: Extracting information from the 'Assigned Modifications' column in psm.tsv. [Assigned Modifications] variable modifications (listed by mass in Da) with modified residue and location within the peptide.Peptide Length Distribution

Standard Deviation of Intensity
Standard deviation of intensity by sample (experimental conditions).
[DIA-NN: report.tsv] Sample grouping is derived from the SDRF when available;
otherwise, it is parsed from "Run" names.
First, identify the experimental conditions from the "Run" name.
Then, group the data by experimental condition and Modified.Sequence, and calculate
the standard deviation of log2(Precursor.Quantity).

MS1 Analysis
Total Ion Chromatograms
MS1 quality control information extracted from the spectrum files.
This plot displays Total Ion Chromatograms (TICs) derived from MS1 scans across all analyzed samples.
The x-axis represents retention time, and the y-axis shows the total ion intensity at each time point.
Each colored trace corresponds to a different sample. The TIC provides a global view of the ion signal
throughout the LC-MS/MS run, reflecting when compounds elute from the chromatography column.

MS1 TIC Proxy
This plot monitors sample loading consistency by tracking the log2-transformed median of summed peak intensities for MS1 spectra,
ordered by acquisition time.
For each run, the summed_peak_intensities from all ms_level: 1 spectra are extracted.
The median value is calculated and log2-transformed to provide a robust representative of the Total Ion Current (TIC) per run.

MS2 and Spectral Stats
Number of Peaks per MS/MS spectrum
Histogram of number of peaks per MS/MS spectrum.
Too few peaks may indicate poor fragmentation; many peaks could indicate noisy spectra.
Peak Intensity Distribution
Histogram of ion intensity vs. frequency for all MS2 spectra.
High number of low intensity noise peaks expected; disproportionate high signal peaks may indicate issues.
Distribution of Precursor Charges

RT Quality Control
IDs over RT
Distribution of retention time, derived from the main report.
[DIA-NN: main report] Distribution of retention time (RT) for each run.
This plot allows to judge column occupancy over retention time. Ideally, the LC gradient is chosen such that the number of identifications (here, after FDR filtering) is uniform over time, to ensure consistent instrument duty cycles. Sharp peaks and uneven distribution of identifications over time indicate potential for LC gradient optimization. See [Moruz 2014, DOI: 10.1002/pmic.201400036](https://pubmed.ncbi.nlm.nih.gov/24700534/) for details.
