The main goal is that when I am trying to make use of the GetQuantiles method, I do not know how to pass the pointers needed by the method.

```
import matplotlib.pyplot as plt
import numpy as np
import sys, os
from scipy.interpolate import interp1d
import matplotlib.colors as colors
import matplotlib.cm as cmx # Colormap
import seaborn as sns
from root_numpy import root2array, tree2array
import root_numpy as rnpy
import ROOT
import h5py
...
fname = 'ts_dist_log_l70_b100_ch0_mass' + str(m) + '.root'
fInp = ROOT.TFile(path + fname)
histBG = fInp.Get('hTS_0')
prob=0.5
y=0.
q=0.
y=histBG.GetQuantiles(1,q,prob)
```

But I get this error.

```
TypeError Traceback (most recent call last)
<ipython-input-34-b618e70e1565> in <module>()
33 q=0.
34
---> 35 y=histBG.GetQuantiles(1,q,prob)
36
37 print(histBG.Integral())
TypeError: int TH1::GetQuantiles(int nprobSum, double* q, const double* probSum = 0) =>
could not convert argument 2
```

So… How I have to pass this arguments to that function?
