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.

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.

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.
