I'm trying to load my first spectrum file with Xspec command within python, aka PyXspec. But PyXspec tell me that it cannot read the response file 'file.rmf'. My basic code is the follow:

from xspec import *

sp1=Spectrum('File_grp.pi')

AllData.show()

It is wired because, if i load the same file in the standard interactive Xspec mode, it works wihtout errors. Something like this:

unix> Xspec
xspec12> data 1:1 file_grp.pi

Try deleting and replacing your response file, like sp1.response = None and then sp1.response.frm = "file.rmf"
