As the peaks of certain spins overlap to such an extent that the heights or volumes cannot be resolved, a simple text file was created called ``unresolved'' in which each line consists of the residue number followed by the atom name. By using the command
[firstnumber=30] # Deselect unresolved spins. deselect.read(name, file='unresolved', res_num_col=1, spin_name_col=2)
all spins in the file ``unresolved'' are excluded from the analysis.
