Read Hessian(numerical frequency) from HDF5

Dear molcas users,

How can i read the hessian from the .h5 file produced by slapaf at the end of numerical freq calculation ?
My aim is start to start an optimization , and use RUNOLD and OLDForce to read hessian from a previous frequqncy calculation. I try to link/copy the *slapaf.h5 as RUNOLD , but molcas complains it to be not a valid runfile.

Re: Read Hessian(numerical frequency) from HDF5

HDF5 is still pretty much a work in progress in all modules, and there is very limited support in SLAPAF. You could try manually writing the Hessian with FCON.
