Hello, I am having a little trouble with the hep.analysis package. I am trying to compile the examples on: http://www-sldnt.slac.stanford.edu/nld/reconstruction/EnergyFlow/JAS/ in JAS3. However, I am receiving compiler errors for the hep.analysis.partition.FixedPartition2D class as follows: /afs/slac.stanford.edu/u/br/nijusan/showerlibs/TrackCellAssociationAnalyzer.java:199: cannot resolve symbol symbol : class FixedPartition2D location: class TrackCellAssociationAnalyzer (new FixedPartition2D(-20.*dtheta,20.*dtheta,40,-20.*dphi,20.*dphi,40)); It also has trouble finding the following functions in the hep.analysis.Histogram class: /afs/slac.stanford.edu/u/br/nijusan/showerlibs/TrackCellAssociationAnalyzer.java:309: cannot resolve symbol symbol : method fillW (double,double,double) location: class hep.analysis.Histogram histogram("EM Layer"+calCell.getLayer()+" ThetavsPhi").fillW(cellTheta-theta,cellPhi-phi,cellEnergy); ^ /afs/slac.stanford.edu/u/br/nijusan/showerlibs/TrackCellAssociationAnalyzer.java:401: cannot resolve symbol symbol : method getPartition () location: class hep.analysis.Histogram FixedPartition2D p = (FixedPartition2D) histogram(type+" Layer"+layer+" ThetavsPhi").getPartition(); Are there some differences between JAS2 and JAS3 when dealing with the hep.analysis package? -Brandon Drummond
