[Users] Error running single star simulation

[Alessandro Ciarfella]

Hello everyone,

I'm Alessandro Ciarfella, a Ph.D. student at the Rochester Institute of 
Technology. I was trying to run the single star simulation example on 
ubuntu installed on a virtual box but after I submit the simulation and 
run the python code to plot the output either from inside the Cactus 
directory or the home directory the following error message appears:

/bin/sh: 1: /home/alessandro/simulations/tov_ET/output-0002: Permission 
denied
Output is written to
Traceback (most recent call last):
   File "tov_ET.py", line 9, in <module>
     lin_data = np.genfromtxt(outdir+"/tov_ET/hydrobase-rho.maximum.asc")
   File 
"/home/alessandro/.local/lib/python3.8/site-packages/numpy/lib/npyio.py", 
line 1793, in genfromtxt
     fid = np.lib._datasource.open(fname, 'rt', encoding=encoding)
   File 
"/home/alessandro/.local/lib/python3.8/site-packages/numpy/lib/_datasource.py", 
line 193, in open
     return ds.open(path, mode, encoding=encoding, newline=newline)
   File 
"/home/alessandro/.local/lib/python3.8/site-packages/numpy/lib/_datasource.py", 
line 533, in open
     raise IOError("%s not found." % path)
OSError: /tov_ET/hydrobase-rho.maximum.asc not found.

I would highly appreciate some help on this. Thanks in advance.

Cheers,

Alessandro Ciarfella
