Dear all,
I have a peptide with few non-standard amino acid residues which I made
using RED server and carried out this 100 ns long simulation. All other
analysis like time-evolution of Hydrogen bonds and RMSD is calculated
without errors. But while calculating phi-psi angles as a function of time
it only calculates for three residues each. These 3 residues are the
standard ones.
Phi-4, Phi-5, Phi-15 and Psi-3, Psi-4, Psi-14
The error for other angle calculation is "one or more atom masks have no
atoms"
I believe it can be due to a different atom numbering convention being
used, like CA is C1 and C is C6 or C7 etc. The same happens when I compute
these angles using the Python MDtraj online module. How can I change this
in a trajectory? Is it possible?
Thanks in advance
