Hmm - there are programs which give you the matrix associated with Eulerian or Polar angles. I think one is pdbset..
Or there is documentation in polarrfn or rotmat which describes how to do it.. But remember there are conventions about which axes correspond to the orthogonal X Y Z axes used to define the angles Eleanor On 18 May 2015 at 17:04, Chen Zhao <c.z...@yale.edu> wrote: > Hi all, > > I am now trying to convert the NCS axis expressed by theta, phi, chi (or > alpha, beta, gamma) from MOLREP to an orthogonal matrix in order to feed > into SOLVE.
