A Python application that is capable of performing multiple structural alignments on incredibly large numbers of three-dimensional protein structures that are not normally able to be done using traditional methods. Utilizes a strategy that leverages multiple pairwise alignments against a single reference.
ABeRMuSA stands for "Approximate Best Reference Multiple Structure Alignment", alluding to the fact that a best reference is chosen through an exhaustive or approximate method and aligned in a pairwish fashion to all other structures in a given set of structures in order to develop an alignment.
Running the following command while in this directory should install the ABeRMuSA executable to your /usr/bin/ directory.
python setup.py install
If you have any problems installing the software, e-mail the author or submit an issue.
ABeRMuSA protein1.pdb protein2.pdb ... proteinN.pdb
A number of options are available, including initiating the heuristic (rather than exhaustive) search for a best reference by using the "-q" option and a number of iterations (or different references to try). You can always type "-h" in your command when executing the program in order to see all possible options. Typical behavior of the software will output a final PDB alignment file, in addition to a number of other auxiliary files such as a FASTA alignment and logfile, with a prefix of the user's choice.
