Failed to create a complete set of delocalised internal coordinates

[eneas77]

Hi,

Running a TS search of a LDA deprotonation of a carbonyl compound, the following error appears halting the TS calculation:

"RuntimeError: Failed to create a complete set of delocalised internal coordinates. 125 < 3 N_atoms - 6. Likely due to missing primitives"

This happens after conformer calculation, at the TS stage, in both versions 1.4.1 & 1.3.5.

Any help will be appreciated.

Thanks.

Hi,

v1.4.2 still fails in this. Any hints about what is going on?

Thanks

@eneas77 Does this happen during the adaptive path search, or during the TS optimisation? (If the adaptive path worked correctly, there should be a <hash>_hl_ad_<num>.xyz, or <hash>_ll_ad_<num>.xyz file in the transition_states folder (or a subfolder inside. The <hash> is alphanumeric and the <num> is a series of numbers.)

@shoubhikraj The following is a snapshot of the TS folder files:

My guess is it happens during the TS opt.

Thanks
