[molpro-user] AIMS not reading inital momenta

Dear molpro users/developers,

I'm trying to perform a AIMS trajectory specifying initial momenta instead
of doing standard samplings. The problem is that the initial momenta given
is not being read. The corresponding files are as follow:

*Geometry.dat:*

aims,dir='.'

-------------------------------------------

In the output E.dat, the EKineticCl is always 0.0 for the initial step, and
the all the momenta outputed TrajDump.1 are 0.0 for time 0, regardless my
input in Geometry.dat.

Any help will be very appreciated.

Best wishes,

Gabriel
