MassIVE Reanalysis - RMSV000000249.2

MassIVE.Quant-Reanalysis-MaxQuant

Description

MS/MS spectra were searched using MaxQuant (v1.5.1.2) and Andromeda as search engine. Acquired data were searched against a concatenated database containing all the UPS human spike-in proteins and all reviewed E.coli K-12 (Taxonomy ID 83333) proteins in Unipro(downloaded November 2015). Precursor ion mass tolerance was set to 4.5 ppm at the MS1 level and to 0.5 Da at the fragment ion level. Up to three missed cleavages for trypsin were allowed. Oxidation of methionine and protein N-terminal acetylation were considered as variable modifications, whereas carbamidomethylation on cysteines was set as a fixed modification. False discovery rate (FDR) in peptide and protein identification was evaluated by using a decoy database and it was set to a maximum of 1%. All identified peptides were quantified with MaxQuant's LFQ algorithm, with the 'match between runs' option activated using a matching time window of 0.7 min and an alignment time window of 20 min. PSM areas were extracted with the intensity extraction algorithm of MaxQuant. The differential abundance analysis was performed by MSstats (v3.13.5) R package. Details for data processing and statistical analysis are available in description.pdf ('Methods' folder). **Publication : Choi et al. (Under revision) MSstats increases the reproducibility of detecting differentially abundant proteins across tools that process raw mass spectra. [doi:10.25345/C56Q8N]

Number of distinct conditions analyzed in this reanalysis.

Distinct condition labels are counted across all files submitted in the "Metadata" category having a "Condition" column in this reanalysis.

"N/A" means no results of this type were submitted.
Number of distinct biological replicates in this reanalysis.

Distinct replicate labels are counted across all files submitted in the "Metadata" category having a "BioReplicate" or "Replicate" column in this reanalysis.

"N/A" means no results of this type were submitted.
Number of distinct technical replicates in this reanalysis.

The technical replicate count is defined as the maximum number of times any one distinct combination of condition and biological replicate was analyzed in files submitted in the "Metadata" category. In the case of fractionated experiments, only the first fraction is considered.

"N/A" means no results of this type were submitted.
Originally identified proteins that were automatically remapped by MassIVE to proteins in the SwissProt human reference database.

"N/A" means no results of this type were submitted.
Number of distinct protein accessions reported in this reanalysis.

"N/A" means no results of this type were submitted.
Number of distinct unmodified peptide sequences reported in this reanalysis.

"N/A" means no results of this type were submitted.
Number of distinct peptide sequences (including modified variants or peptidoforms) reported in this reanalysis.

"N/A" means no results of this type were submitted.
Total number of peptide-spectrum matches (i.e. spectrum identifications) reported in this reanalysis.

"N/A" means no results of this type were submitted.
Number of distinct proteins quantified in this reanalysis.

Distinct protein accessions are counted across all files submitted in the "Statistical Analysis of Quantified Analytes" category having a "Protein" column in this reanalysis.

"N/A" means no results of this type were submitted.
Number of distinct proteins found to be differentially abundant in at least one comparison in this reanalysis.

A protein is differentially abundant if its change in abundance across conditions is found to be statistically significant with an adjusted p-value <= 0.05 and lists no issues associated with statistical tests for differential abundance.

Distinct protein accessions are counted across all files submitted in the "Statistical Analysis of Quantified Analytes" category having a "Protein" column in this reanalysis.

"N/A" means no results of this type were submitted.
