I have several conformers for which I wanted to plot the averaged weighted spectra. The number of atoms are same. However, the atom numberings are different. As a result, the spectra I am getting is incorrect. Is there any quick way to resolve this issue ? or can I use a bash script where I process multiple output files and generate the spectra of all the conformers and then average the spectra.

Thanks,
