Hello Janikiraman,

  sometimes such a segmentation fault is caused by a low setting for the 
stack size limit in your shell. If you use bash, you should set "ulimit 
-s unlimited" before running smeagol. I also had a look at your input 
file, and in general it is OK, just you have to change the number of 
imaginary energy points. In your file you use 0 for the number of poles, 
which will not work, since you need at least a few poles. For a room 
temperature calculation I suggest to use:
EnergImCircle           16
NEnergImLine           16
NPoles                       16

Cheers,

 Ivan
