Dear Vidhyh Sankar,
>IndexError: list index out of range
When a program reads in lists or arrays, in the software there is usually a set size, for lines or number of atoms, etc... If the array or list is longer than the set value you get this error. Also, if a counter is off, ie stops one short through an iteration usually from not reading lines properly or geting a returned length for an index which has changed in length...
It either means one of the following:
2 of your files dont match in size (ie number of atoms)
1 of your files has the formatting wrong, ie lines are speced too long, so it doesnt read them properly
or theres a problem with the script, where it gets incorrect index lenghts.
if you look at the lines mentioned in the setupUmbrella.py script, it will tell you exactly what it is trying to read in, and you can then either know if its missmatch, or your files are formatted wrong.
Id wait and see, somone might be able to tell you off the bat exactly what the error is though. In my experience, it can often be a secound carriage return or space at the end of a .gro, or .dat or .sh file.
