   qmean is a statistical measure used in the evaluation of protein models, particularly in homology modeling. It assesses the quality of a model by providing a quantitative score that reflects how well the predicted structure aligns with known reference structures.

7. People also ask

   What does QMEAN stand for?

   • QMEAN, which stands for Qualitative Model Energy ANalysis, is a composite scoring function describing the major geometrical aspects of protein structures. Five different structural descriptors are used. The local geometry is analyzed by a new kind of torsion angle potential over three consecutive amino acids.

   What is qmeanbrane?

   • QMEANBrane is a combination of statistical potentials targeted at local quality estimation of membrane protein models in their naturally occurring oligomeric state: after identifying the transmembrane region using an implicit solvation model, specifically trained statistical potentials get applied on the different regions of a protein model.

   Who can use the QMEAN server?

   • The QMEAN server addresses both users of protein structure models as well as method developers. The user of the web server has the possibility to either assess a single model or multiple models. Each model is assigned a quality score which is used to rank the structures.
