I have a bunch of histograms I want to save. I create a file then loop through the histograms to save them, but for some reason I get this message:
Error in TROOT::WriteTObject: The current directory (PyROOT) is not associated with a file. The object (FLMT034741_16-17-44-413) has not been written.
I get it once for every histogram that I want to save.
The weird part is that the file is indeed created and it is in the directory it should be, and yet I cannot get the histograms to be written on it.
The relevant part of the code is this:
file = root.TFile('OceanView.root','recreate') #create place to save histograms for file in ourFiles: name = file[0:len(file)-4] #the name has the .txt extension, so I remove it [v1, v2] = aTv.getVectors(directory+'/'+file) #this function extracts the data from the .txt file histogram = vTh.histo(v1,v2,name) #this function takes the data from the .txt file and creates an object that, among other things contains the histogram histogram.hist.Write() #I want to save the histogram
The functions I use work as intended, I have tried them individually and I hadn’t had any problems
