Hi everyone,

A little problem, actually, I am trying to define vectors (at arbitrary
points) in space in VMD. Like,

set temp_vector {1 2 3}, now in place of 1,2,3 i.e. x,y and z, I would like
to put some variables, which are defined and are taking value from
somewhere, specifically to say, set temp_vector {$a $b $c},can something of
that kind be done in VMD? I couldnt make it work it like that atleast.
Please reply if you have any ideas, once again to say, I have to define many
arbitrary vectors in space, without a pdb i.e. no lindex, etc.
