Non-helpfull error region length

[JGASmits]

When running ananse binding with a region file with regions of only 1bp length, the error is not very descriptive:

I'm rerunning it now in order to see if adjusting region length fixes the issue. Ill comment once I'm sure the region lengths were the problem.

Ideal would be if with smaller region length ananse would resize the regions like some gimme motif tools. Alternatively an more insightfull error would be nice.

It was indeed the region lenght that was the problem. :)
