MODELLER
MODELLER is a method for comparative protein structure modelling, provided by satisfaction of spatial restraints. In the simplest case, the most probable structure for a given sequence can be found based on its alignment with related structures. Additional to model building, MODELLER can perform several other tasks including fold assignment, pairwise/ multiple alignments of protein sequences, calculation of phylogenetic trees, and de novo modeling of loops in protein structures. The method was published by Sali and Blundell in 1993. <ref>A. Sali & T.L. Blundell. Comparative protein modelling by satisfaction of spatial restraints. J. Mol. Biol. 234, 779-815, 1993.</ref>

SWISS-MODEL
SWISS-MODEL workspace was published by Arnold et al. in 2005. <ref> Arnold K., Bordoli L., Kopp J., and Schwede T. (2006). The SWISS-MODEL Workspace: A web-based environment for protein structure homology modelling. Bioinformatics, 22,195-201.</ref>
Results
Using the standard output alignment of ClustalW2, the workunit of Swiss-Model got aborted: too many unfruitful attempts to rebuild a loop were tried. This indicates, that the alignment is not good and that it has to be adjusted.
