Hi
I always work with ROOT in ubuntu, but recently due to some hardware issue in my laptop i have been pushed to work in Windows. I installed Root 5.32 in windows 7, location (C:/Root).
I have two completely different question.
-
As my root directory is C:/Root whenever i start root the default working directory is the same, but my root files and histograms are in different directory(different partition). I wonder how can i change my working directory?
-
As i didnt know answer my the first question, i changed my root macro which reads the root file as
TFile *f = new TFile(“path/to/the/file/output24_B_0_histo.root”);
and in root i did .x path/to/the/macro.C
This macro uses roofit to fit a histogram, i used RooChebychev and Roogaussian and the parameters are set in such a way that it did a perfect fit when i ran it in ubuntu, but when i ran it in Windows the Minuit was keep on running and never stopped and i believe it couldnt optimize the fit ever!
I am not sure why is that, is there any component i missed to install?
