MolecularFeaST
The Molecular Feature Selection Tool (MolecularFeaST) is a free-to-use, standalone application that streamlines the use of our feature selection algorithm. MolecularFeaST has been used to find biomarkers based on numerous -omics profiles including: RNA-seq, small RNA-seq, RT-qPCR data, NanoString profiling, microarray data, srRNA expression, bisulfite (DNA methylation) sequencing, and protein mass spectroscopy.
