[Pw_forum] from invmat : error #1 singular matrix

[Lim Chiang Huay, Freda]

Dear all,

I am trying to run NEB to find out the activation energy required to transform one configuration (sandwiched) of a sandwich-molecular wire to another configuration (zigged-zagged).

And I get this error msg:

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
     task #         3
     from  invmat  : error #         1
      singular matrix
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

I can't find any clue as to what's wrong with my job from previous forum postings.

Can anyone help?

Thanks,
Rgds
