[molpro-user] How to Avoid 'ERROR IN VIRTORB: INCORRECT NUMBER OF ORBITALS' without using start, atden

[Kirk Peterson]

Dear Sachin,

this seems to be an unusual error to me.  One needs to understand why the number of virtuals are changing from one geometry to another. Have you changed the basis set or perhaps even the molecule?

regards,

-Kirk
