Bug when there are zero Snps or zero indels

[ml31k]

Hi,

I've run into another bug which occurs when there are either zero Snps or zero Indels.
The program will not reach any of the process_event steps, even if there are Snps / indels (but not both)
It's probably not an error that would occur using the whole dbSNP (but did come up when i was testing with a subset)

Error:
