Wessim and exome read simulation

Question

[bdelolmo]

Hello,

I am trying to do some exome-seq simulations with Wessim but without success. I can run the command without warnings, but when manually inspecting the reads with IGV I see them accumulated on the start and end coordinates for every targeted region (pic attached). https://ibb.co/f78drQ

I have tried it in ubuntu 12.04 and 14.04 with the same issues. So I am wondering if this is an error within the package or If It it just does not work on my distribution.

Many thanks ,
