"discover" output file field <otCount> format issue

[moritzschaefer]

The format of the field is a character instead of an int.
Example: Analyzing the BRD4 gene, I get for the first target 90 off-targets. Though in the otCount, a 'Z' is written (which has the value 90 in ASCII). For this reason the scoring step fails (as it can't interpret the character).

The issue is here:

https://docs.oracle.com/javase/7/docs/api/java/io/PrintWriter.html
says
void | write(int c): Writes a single character.

So a int-to-string conversion is necessary there.

How comes you didn't stumble upon this issue?

This bug was just introduced in commit 5b2d3890ab929bc87bcd5d0b06e71bff8ed4c704 where I switched from a write(int + string), which writes a string, to a write(int). I didn't put unit testing in for the output, something I should do.
