If the peptide sequences should be distinguished based on post-translational modifications, this column can be renamed to PeptideModifiedSequence. + - PeptideSequence: Amino acid sequence for each peptide. If the peptide sequences should be distinguished based on post-translational modifications, this column can be renamed to PeptideModifiedSequence. - PrecursorCharge: charge state of precursor. - FragmentIon: e.g. b4, y3, if unknown use a single value for all entries. - ProductCharge: charge state of product. If unknown use 0 for all entries. - IsotopeLabelType: This column indicates whether this measurement is based on the endogenous peptides (use “L”) or labeled reference peptides (use “H”). - - Condition: For group comparison experiments, this column indicates groups of interest (such as “Disease” or “Control”). For time-course experiments, this column indicates time points (such as “T1”, “T2”, etc). If the experimental design contains both distinct groups of subjects and multiple time points per subject, this column should indicate a combination of these values (such as “Disease_T1”, “Disease_T2”, “Control_T1”, “Control_T2”, etc.). + - Condition: For group comparison experiments, this column indicates groups of interest (such as “Disease” or “Control”). The name of the condition is not allowed to start with a number or contain any special characters. For time-course experiments, this column indicates time points (such as “T1”, “T2”, etc). If the experimental design contains both distinct groups of subjects and multiple time points per subject, this column should indicate a combination of these values (such as “Disease_T1”, “Disease_T2”, “Control_T1”, “Control_T2”, etc.). - BioReplicate: This column should contain a unique identifier for each biological replicate in the experiment. For example, in a clinical proteomic investigation this should be a unique patient id. Patients from distinct groups should have distinct ids. MSstats does not require the presence of technical replicates in the experiment. If the technical replicates are present, all samples or runs from a same biological replicate should have a same id. MSstats automatically detects the presence of technical replicates and accounts for them in the model-based analysis. - Run: This column contains the identifier of a mass spectrometry run. Each mass spectrometry run should have a unique identifier, regardless of the origin of the biological sample. In SRM experiments, if all the transitions of a biological or a technical replicate are split into multiple “methods” due to the technical limitations, each method should have a separate identifier. When processed by Skyline, distinct values of runs correspond to distinct input file names. It is possible to use the actual input file names as values in the column Run. - Intensity: This column should contain the quantified signal of a feature in a run without any transformation (in particular, no logarithm transform). The signals can be quantified as the peak height or the peak of area under curve. Any other quantitative representation of abundance can also be used. @@ -695,26 +948,32 @@ ... ... ... ... ... isotopelabeltype condition bioreplicate run intensity - L 1 ReplA 1 4298.12 - H 1 ReplA 1 1974.59 - L 1 ReplA 1 7183.22 - H 1 ReplA 1 8467.58 + L disease ReplA 1 4298.12 + H disease ReplA 1 1974.59 + L disease ReplA 1 7183.22 + H disease ReplA 1 8467.58 ... ... ... ... ... + - MaxQuant format: evidence.txt, proteinGroups.txt; plus externally generated annotation file + - OpenSWATH format: pyprophet export file; plus externally generated annotation file - Annotations as tabular file are needed for all input options except MSstats format - 4 columns with exactly these headers: Raw.file, Condition, BioReplicate, Run; additional 5th column only for MaxQuant: IsotopeLabelType - - Raw.file: File name that has to match exactly as it appears in the other input files (e.g. S1207.raw.thermo; in/AA12_mzML.mzML) - - all other columns: see description above for MSstats format columns + - Raw.file: + + - OpenSWATH: File name needs to fit exactly how it is written in OpenSwatch output (e.g. "in/AA12_mzML.mzML") + - MaxQuant: File name needs to fit to how it is written in MaxQuant output, but the ".raw" has to be removed (e.g. "file1.raw.thermo.raw" --> "file1.raw.thermo") + - Condition: The name of the condition is not allowed to start with a number or contain any special characters + - All other columns: see description above for MSstats format columns - Comparison matrix as tabular file - 1st column: name of comparison - - additionally one column for each condition that is present in the tabular file.
