Overview

FragPipe-Analyst

FragPipe-Analyst is an easy-to-use, interactive web application developed to perform differential expression analysis with “one click” and to visualize quantitative proteomic datasets analyzed using FragPipe computational platform. It is compatible with the LFQ-MBR, TMT, and DIA quantification workflows in FragPipe. FragPipe-Analyst is based on the original LFQ-Analyst code.

Getting Started

Quick Start

  • Choose the type of experiment you performed. Currently, DDA-based LFQ (MS1-based or spectral count), TMT, and DIA are supported. Users could also choose to perform analysis at the protein or peptide levels.
  • For DDA LFQ:
    • For protein: Upload combined_protein.tsv generated by IonQuant in FragPipe
    • For peptide: Upload combined_peptide.tsv generated by IonQuant in FragPipe
    • Upload experiment_annotation.tsv file. Edit the template file generated by FragPipe; Check here for details.
    • Select quantification method (MS1-based Intensity or MaxLFQ Intensity, or spectral counts).
  • For TMT:
    • For protein or gene: Upload gene-level report [abundance/ratio]_gene_[normalization].tsv or protein-level report [abundance/ratio]_protein_[normalization].tsv generated by TMT-Integrator (TMT-I) in FragPipe (we recommend abundance_gene_MD.tsv file). If peptide option is enabled in the server, TMT-I peptide report could also be used alternatively.
    • For peptide: Upload peptide-level report [abundance/ratio]_peptide_[normalization].tsv generated by TMT-Integrator (TMT-I) in FragPipe (we recommend abundance_peptide_MD.tsv file). If peptide option is enabled in the server, TMT-I peptide report could also be used alternatively.
    • Upload experiment_annotation.tsv file. Edit the template file generated by FragPipe; Check here for details.
  • For DIA:
    • For protein: Upload protein group (PG) matrix ( diann-output.pg_matrix.tsv ) generated by DIA-NN in FragPipe
    • For peptide: Upload precursor group matrix ( diann-output.pr_matrix.tsv ) generated by DIA-NN in FragPipe
    • Upload experiment_annotation.tsv file. Check here for details.
  • Optional: Adjust the missing value filter, normalization, missing value imputation, p-value cut-off, the log2 fold change cut-off, FDR correction method in the Advanced Options . Note that the missing value imputation method is set by default to “Perseus-like” for DDA LFQ and DIA, and to “No imputation” for TMT.
  • Press 'Run'
  • Hint: Check the Documentation tab for a detailed explanation of inputs, advanced options and outputs
