  2. Why Prequips for Systems Biology with proteomic data? • Need for visualization, analysis, and integration of multiple proteomic datasets: raw data level, peptide level, protein level, multi sample analysis • Need for an interface between proteomic data and systems biology analytical tools such as network/pathway analyses

  3. Integration of proteomic data at various levels ? ? ? Communication not possible! Protein Id + Quantitation Protein Id + Quantitation Protein Id + Quantitation Trans-Proteomic Pipeline Trans-Proteomic Pipeline Trans-Proteomic Pipeline Peptide Id + Quantiation Peptide Id + Quantiation Peptide Id + Quantiation Raw Data (MS, MS/MS) Raw Data (MS, MS/MS) Raw Data (MS, MS/MS)
