QCS

Quality Control Score for structure prediction quality assessment.
Quality Control Score (QCS) is a new method to evaluate the quality of structure predictions, especially for template free structure prediction. It was developed to mimic visual inspction by human expert and it captures both global and local structural features, with emphasis on global topology.

SCG

Self Consistency Grouping.

SCG clusters whose members are closer in rank to each other than to any member outside the cluster. SCG does not take any additional parameters and consequently does not impose any restriction on the size or the number of the clusters that it finds, since the natural boundaries of clusters are determined by the inconsistencies in the ranks.

HangOut

HangOut removes "overhangs", which are erroneously extended during PSI-BLAST runs caused by long insertions or inserted domains, and builds clean profiles for those domains.

PROMALS3D

PROfile Multiple Alignment with predicted Local Structure and 3D constraints.
PROMALS3D is a multiple sequence and structure alignment program. It uses 3D structure superpositions where available and information from database searches and secondary structure predictions. According to our tests, PROMALS3D is currently the most accurate multiple alignment program available. Please let us know, if you find this is no longer the case.

WinDiso

WINdow-based DISOrder preditor.
WinDiso is a linear, sequence- and alignment-based predictor of disordered/unfolded regions in proteins. It has the capability of adjusting for the increased tendency for disorder at protein termini. The simple weighted window-based algorithm and careful optimization technique make this a good predictor to use when trying to avoid bias toward special cases. WinDiso was optimized using several thousand crystallographic structures. Analysis of its optimized parameters has provided insight into physical principles involved in order/disorder.
