Hi,
as my question already indicates I would like to do some multivariate analysis of my proteomics data as I have multiple characteristics in my samples. I have successfully used MetaboAnalyst for multivariate analysis in metabolomics approaches. Do I have to expect some drawbacks by using MetaboAnalyst for proteomics data or is there an easy tool such metaboAnalyst for proteomics data?
Thank you for your help!
BR,
Timo
MetaboAnalyst is primarily designed for metabolomics data analysis, but it also supports proteomics data analysis. Therefore, it is possible to use MetaboAnalyst for multivariate analysis of proteomics data, but there may be some limitations.
One potential issue is that the data preprocessing methods for proteomics data might differ from those used for metabolomics data. For example, the normalization and scaling methods for proteomics data might not be the same as those used for metabolomics data. Additionally, the statistical tests available in MetaboAnalyst might not be optimized for proteomics data.
However, despite these limitations, MetaboAnalyst is still a powerful tool that can be used for proteomics data analysis. It provides a user-friendly interface for data uploading, preprocessing, and multivariate analysis. It also supports a wide range of multivariate analysis techniques, including PCA, PLS-DA, OPLS-DA, and clustering analysis, which can be used to identify patterns and relationships in the data.
If you are looking for a specialized tool for proteomics data analysis, there are other software packages available, such as Progenesis QI for Proteomics, MaxQuant, and Perseus. These tools are designed specifically for proteomics data analysis and offer a wide range of advanced features and analysis methods.
Thank you for the answer. In addition, I found an article that was combining Perseus and MetaboAnalyst for statistical analysis of proteomics data. They used MetaboAnalyst for PLS-DA.

If I get it correctly, after preprocessing the proteomics data it seems possible to forward the data to MetaboAnalyst using the peak intensities of the proteins for further MVA
Yes, that's correct! After preprocessing your proteomics data (e.g., normalization, missing value imputation, batch effect correction, etc.), you can use the peak intensities of the proteins as features for further multivariate statistical analysis (MVA) using MetaboAnalyst.
To use MetaboAnalyst for proteomics data analysis, you will need to convert your peak intensity data into a suitable format (e.g., comma-separated values (CSV) or tab-separated values (TSV)) and upload it to the platform. You can then choose from a range of statistical and machine learning methods to analyze your data and identify patterns and relationships between the proteins and experimental conditions.
