Hi everybody,
I am trying to fill a TTree with date from a csv file. The Date in the csv file are same floats.
This is my code:
import ROOT
import numpy as np
#------------------------ CSV --------------------------
data = open("./Daten_csv/daten.csv", "r")
#------------------------ ROOTFILE --------------------------
outputfile = ROOT.TFile("./Daten_root/test.root", "RECREATE")
T1 = ROOT.TTree("T1","ROOT tree brachnes for T1")
T2 = ROOT.TTree("T2","ROOT tree brachnes for T2")
#------------------------ Variables -----------------------------
var1_T1 = np.zeros(1)
var2_T1 = np.zeros(1)
var3_T1 = np.zeros(1)
var4_T1 = np.zeros(1)
var5_T1 = np.zeros(1)
var6_T1 = np.zeros(1)
var7_T1 = np.zeros(1)
var1_T2 = np.zeros(1)
var2_T2 = np.zeros(1)
var3_T2 = np.zeros(1)
var4_T2 = np.zeros(1)
var5_T2 = np.zeros(1)
var6_T2 = np.zeros(1)
var7_T2 = np.zeros(1)
#-----------------------------Branches---------------------------------------
T1.Branch("var1_name",var1_T1,"I")
T1.Branch("var2_name",var2_T1,"I")
T1.Branch("var3_name",var3_T1,"I")
T1.Branch("var4_name",var4_T1,"I")
T1.Branch("var5_name",var5_T1,"I")
T1.Branch("var6_name",var6_T1,"I")
T1.Branch("var7_name",var7_T1,"I")
T2.Branch("var1_name",var1_T2,"I")
T2.Branch("var2_name",var2_T2,"I")
T2.Branch("var3_name",var3_T2,"I")
T2.Branch("var4_name",var4_T2,"I")
T2.Branch("var5_name",var5_T2,"I")
T2.Branch("var6_name",var6_T2,"I")
T2.Branch("var7_name",var7_T2,"I")
# I dont wanna have the first line from the csv
counter = 0
for line in data:
if counter == 0:
counter = 1
else:
# I the difference between T1 and T2 is stored in column 1 from the csv file
if float(line.rstrip().split(",")[0]) == 0:
var1_T1[0] = float(line.rstrip().split(",")[1])
var2_T1[0] = float(line.rstrip().split(",")[2])
var3_T1[0] = float(line.rstrip().split(",")[3])
var4_T1[0] = float(line.rstrip().split(",")[4])
var5_T1[0] = float(line.rstrip().split(",")[5])
var6_T1[0] = float(line.rstrip().split(",")[6])
var7_T1[0] = float(line.rstrip().split(",")[7])
T1.Fill()
else:
var1_T2[0] = float(line.rstrip().split(",")[1])
var2_T2[0] = float(line.rstrip().split(",")[2])
var3_T2[0] = float(line.rstrip().split(",")[3])
var4_T2[0] = float(line.rstrip().split(",")[4])
var5_T2[0] = float(line.rstrip().split(",")[5])
var6_T2[0] = float(line.rstrip().split(",")[6])
var7_T2[0] = float(line.rstrip().split(",")[7])
T2.Fill()
T1.Print()
T2.Print()
data.close()
outputfile.Write()
outputfile.Close()The csv looks like this:
SeparationVar, Var1, Var2, Var3, Var4, Var5, Var6, Var7

0,88,55,2,2,2,2,3

0,86,46,2,2,3,2,1
0,86,53,2,2,2,2,3
0,86,75,2,1,2,3,2
0,86,64,1,2,3,2,1
0,86,53,2,2,2,2,3

0,86,53,2,2,2,2,3
0,85,52,2,2,2,2,3
0,86,53,2,2,2,2,3
0,86,53,2,2,2,2,3
0,86,53,2,2,2,2,3
0,86,53,2,2,2,2,3
0,85,52,2,2,2,2,3
1,87,54,2,2,3,3,3
0,86,53,2,2,2,2,3The problem is now that the root file has just histograms with entry-times 0.
Is there something wrong with my code? If I am doing it like this:
import ROOT
import numpy as np
print "Writing a tree"
f = ROOT.TFile("tree.root", "recreate")
t = ROOT.TTree("name_of_ttree", "tree title")
n = np.zeros(1)
t.Branch('gauss', n, 'gauss/D')
for i in xrange(100000):
n[0] = ROOT.gRandom.Gaus()
t.Fill()
f.Write()
f.Close()The Branch looks good.
