Dear All,
I am currently working on calculating the FSAPT interaction energy for the L-DOPA@CB7 complex. This is my first attempt at performing such calculations, and I’m facing an issue that I hope you can help me with.
I aim to calculate the interaction energy between the amine group of L-DOPA and the CB7 molecule for amino acids with different side chain sizes. To achieve this, I’ve successfully calculated the FSAPT0 energy.
Here’s the problem I’m encountering:
I’ve decided to split the L-DOPA ligand at the C-N bond to isolate the amine group. Additionally, I’ve divided the CB7 molecule in half for the analysis. After running the fsapt.py script, I’m getting the following error:
File "/home/maura/psi4conda/share/psi4/fsapt/fsapt.py", line 1085, in <module>
stuff = compute_fsapt(dirname, False)
File "/home/maura/psi4conda/share/psi4/fsapt/fsapt.py", line 925, in compute_fsapt
order2 = extract_order2_fsapt(osapt, total_ws['A'], total_ws['B'], frags)
File "/home/maura/psi4conda/share/psi4/fsapt/fsapt.py", line 503, in extract_order2_fsapt
val = np.einsum('i,ij,j', valueA, value, valueB)
File "/home/maura/psi4conda/lib/python3.10/site-packages/numpy/core/einsumfunc.py", line 1371, in einsum
return c_einsum(*operands, **kwargs)
ValueError: operands could not be broadcast together with remapped shapes [original->remapped]: (204,)->(204,newaxis) (203,452)->(203,452) (453,)->(453)
I would greatly appreciate any guidance or advice on what I might be doing wrong in my calculation setup. If you need additional information, please let me know. I am attaching all files from fsapt folder and cb7_Ldopa.txt (output form fsapt calculations).
Thank you in advance for your help!
