I was trying to read .con file for a transport simulation made with modflow usg, like i can do with hds file.
Is there a way to read .con file using flopy? I tried something like this:

import flopy.utils.binaryfile as bf
con_file = 'results.con'
conobj = bf.HeadFile(con_file, text = 'concentration', precision = 'single')

but i get this error:

File "C:\Users\emunozv\AppData\Local\Continuum\anaconda3\lib\site-packages\flopy\utils\binaryfile.py", line 221, in _get_header
return header[0]

IndexError: index 0 is out of bounds for axis 0 with size 0

I know bf.HeadFile is incorrect, but it was a test. I don't know the header of .con file.

Thanks for helping
