I am trying to do a QM/MM calculation with Molcas with the Tinker-Interface for adenosine. I want to include the adenine in the QM-region and the sugar in the MM-region.
I am using a very reduced input, directly taken from the Molcas-Manual example file and created the xyz-File with Tinker's tool pdbxyz out of a pdb-file, yet I keep on getting the same error, seemingly the calculation does not even start.
Anyways I did tons of various calculations with the Manual-Example trying to find the source of my error, the manual-example ran without any problems with the exact same paths. Only after changing bonds or labeling in the .xyz file, it would give me the same error.
My input files are:
adenosin.inp:
> EXPORT TINKER=$MOLCAS/tinker/bin
> COPY /home.aletheia/vbe/Bachelor/Rechnungen/QMMM/Vorrechnungen/adenosin.xyz $WorkDir/adenosin.xyz
> COPY /home.aletheia/vbe/Bachelor/Rechnungen/QMMM/Vorrechnungen/adenosin.key $WorkDir/adenosin.key

respectively the Errorfile prints:

Can anyone see what the reason for the Error is? Since there is no "File Molcas-10" involved, I am quite clueless at this point.
I would be very happy about any hint. I hope I provided all the necessary information.
Thank you in advance for taking time and dealing with my problem.
Best wishes

What does the file adenosin.Tinker.log say?
Offline
It said that my frontier Bond is not defined correctly. So I realized that the MM does not request the last atom of the QM region, but rather the first atom of the MM region.
Thank you very much for taking the time to read my post and giving me the decisive hint for finding the problem.
Best wishes

I may add a general hint. After having built your xyz and key files, run Tinker utility analyze. It will fail if something is wrong with your files.
