Analyzing clinical samples with liquid chromatography-mass spectrometry (LC-MS) is promising but challenging. This study identifies 10 usability descriptors for freely available LC-MS data analysis software to improve large-scale proteomic data processing.

Area of Science:

Proteomics
Bioinformatics
Analytical Chemistry

Background:

Liquid chromatography-mass spectrometry (LC-MS) is a powerful technique for quantifying protein and peptide abundances in clinical samples.
Analyzing large datasets of clinical samples presents significant computational challenges, necessitating automated data processing.
Developing user-friendly and efficient data analysis software is crucial for advancing proteomic research.

Purpose of the Study:

To identify and propose key usability descriptors for data analysis software used in LC-MS profiling.
To evaluate the usability of four recently introduced, freely available LC-MS data analysis tools.
To provide guidelines for the development and assessment of future proteomic data analysis software.

Main Methods:
