Hi Ed, If you look for example at BSemiExcl-Run1-OnPeak-R14-1.tcl the specified collections are the same old: input add /store/PRskims/R12/14.3.2/BSemiExcl/00/BSemiExcl_0031 new: lappend inputList /store/PRskims/R12/14.3.2/BSemiExcl/00/BSemiExcl_0031%selectEventSequence=1-20000 so they so exist. If I understand correctly, the new tcls don't talk to KanEventInput anymore but I don't know how else to specify an input collection.
