Hi Souleymane,

To see and manipulate the data in the histogram hdf5 file, you can use
the gui app of histogram. First you need to make mcvine available,
which on arcs2 cluster, would be

$ source ~linjiao/mcvine.sh

And then you can bring up the histogram gui app

$ HistogramGUIApp.py

You can then use the menu "File->open" to open the histogram, for
example, He4/iqe.h5

The histogram will be loaded and a plot will show up. In the embedded
python shell window, you can take a slice of a histogram and see its
effect right away. For example, if you want a slice at Q=10:

>>> ie_10 = IQE[{'Q': 10}]

If you want a slice at E = 100:

>>> iq_100 = IQE[{'E': 100}]

You can save the new histogram (slice) you created to a file by using
the "File->Save histogram" menu item,
or save the histogram plot to a image file by using the "File->save
plot" menu item.

More details about histogram package can be found at
http://docs.danse.us/histogram.

I have cc'ed this email to mcvine user group, since it is a quite
generic question. Hope that is OK with you.
