::pwtk::nebi::addImageCoor_fromPWO

SYNOPSIS

proc ::pwtk::nebi::addImageCoor_fromPWO {args} {

USAGE

   ::pwtk::nebi::addImageCoor_fromPWO ?-before | -after? imageIndex pwoFile ?pwoIndex?

PURPOSE

Add a new image's ATOMIC_POSITIONS from the PWO file to the POSITIONS card.

OPTIONS

-before ... add a new image positions before the index-th image
-after ... add a new image positions after the index-th image

ARGUMENTS

imageIndex --- the image's index
pwoFile -- the PWO file from where to load the image's atomic positions
pwoIndex -- (optional) the index of structure in the PWO file (default = end)

EXAMPLE

   ::pwtk::nebi::addImagePos_fromPWO -before 1 relax.out
