AB  - MOTIVATION: Empirical analyses of protein secondary structures based on circular 
      dichroism (CD) and synchrotron radiation circular dichroism (SRCD) spectroscopic 
      data rely on the availability of reference datasets comprised of spectra of
      relevant proteins, whose crystal structures have been determined. Datasets
      comprised of only soluble proteins have not proven suitable for analysing the
      spectra of membrane proteins. RESULTS: A new reference dataset, MP180, has been
      created containing the spectra of 30 membrane proteins encompassing the secondary
      structure and fold space covered by all known membrane protein structures. In
      addition a mixed soluble and membrane protein dataset, SMP180, has been created, 
      which includes 98 soluble protein spectra (SP) plus the MP180 spectra.
      Calculations of both membrane and soluble protein secondary structures using
      SMP180 are significantly improved with respect to those produced, using soluble
      protein-only datasets. The SMP180 dataset also enables determination of the
      percentage of transmembrane residues, thus enhancing the information previously
      obtainable from CD spectroscopy. AVAILABILITY AND IMPLEMENTATION: Reference
