Problem with variability index

[astrolog1986]

Dear All,

I am trying to calculate the variability index but it gives an error (below).
It fails to read the last config file (I tried for several different light curves and
always the problem is with the last bin) but that file exists.

/home/Comp_2/LightCurve_14bins/source_results.dat

Can you please help to solve this problem?

Thank you

Hi

it seems that the LC point 13 failed. did you check the corresponding log file?
cheers

Dear David,

Thank you for your answer! Yes, I checked there is no warning or error (below is the full output from enrico). Also I send the results in source_PowerLaw_444569076_460339203_2240_300000_NS_LC_13.results.

Thanks in advance!

[davidsanchez]

looking at the output the code is trying to open the .results file and can't find it
IOError: [Errno 2] No such file or directory:
'/home/Comp_2/LightCurve_14bins//source_PowerLaw_444569076_460339203_2240_300000_NS_LC_13.results'

did you check on other binnings?

[astrolog1986]

Dear David,

Thank you for your answer! Yes I tried 20 bins but again error in the last been.
Yes it is trying to open the file of the last bin and can not find it but it is there....

Hi
after several test, I want not able to reproduce this problem

did you ran the SED first?
