PROSE: phenotype-specific network signatures from individual proteomic samples
Proteomic studies characterize the protein composition of complex biological samples. Despite recent advancements in mass spectrometry instrumentation and computational tools, low proteome coverage and interpretability remains a challenge. To address this, we developed Proteome Support Vector Enrich...

Proteomic studies characterize the protein composition of complex biological samples.
