Re: [ccp4bb] Classifying Diverse Conformations of Many Structures of a Protein

It's not ccp4, but I've successfully used MultiSeq in VMD to make a 1-dimensional tree from a large group of conformations. Though like you mention, the big conformational changes might not be handled well in the STAMP alignment of that package. ProSMART might be more appropriate if you have rigid

Hi Jacob, Principal component analysis (pca) might work but it will modify the original dimensions as a linear combination, which might make it difficult to derive physical meaning out of it. May be, you could use decision trees which give results that are easier to interpret. Looking at decision

Sounds like a perfect application for principal components analysis. Check out Bio3D: http://thegrantlab.org/bio3d/index.php. Cheers, Tristan Tristan Croll Lecturer Faculty of Health School of Biomedical Sciences Institute of Health and Biomedical Engineering Queensland University of Techno

2015-07-07 Thread Keller, Jacob
Is anyone aware of a way to classify large numbers (100s) of conformationally-diverse crystal structures of a single protein (here calmodulin)? Pairwise RMSD matrixes seem possible, but may be complicated since there are two somewhat stable lobes, and the flexible linker in the middle. What I a
