a Support Vector Machine-based classifier, named Coding Potential Calculator (CPC), to assess the protein-coding potential of a transcript based on six biologically meaningful sequence features.
Coding Potential Calculator distinguish protein-coding from non-coding RNAs based on the sequence features of the input transcripts. Our preliminary performance assessment suggests the CPC can reliably discriminate the coding and non-coding transcripts in ~98% accuracy. We provide an online version of CPC here.
