Structural assessment:
MAIDEN score = -138.5867
The MAIDEN score is aimed at assessing the relative quality, i.e. ranking several models (the lower the score, the better the model). It comes here with a color code (red > yellow > green > blue), which is derived from a z-score calculation and indicates the absolute quality.
