Hi, I have added some instructions to compile and link VubRecoilUser in R18 to our standard instruction page http://www.slac.stanford.edu/BFROOT/www/Physics/Analysis/AWG/InclusiveSL/islrecoil/VubRecoilUser.html. So far the code is successfully compiling and linking. It will read at least one event, if you switch off all MC corrections (set MCCorrections "false" in VubXlnu.tcl), but don't expect that it will reach the last event in the collection.
