Subject: Iterating over motif positions instead of rows, row segments
X-Git-Url: http://git.uio.no/git/?a=commitdiff_plain;h=8c7e6967db75a4076f2a4a37a6b36c6520df5367;p=u%2Fmrichter%2FAliRoot.git

Iterating over motif positions instead of rows, row segments
(this fixes a problem for non-bending plane where some pads
were iterated twice)
