Meaning of tags 't3, t4, t7' etc in fusion description column

[asmitagpta]

Hi,

I am running fusioncatcher v1.33 for a set of RNA-Seq data. I noticed that the output file for many of the samples contain fusions with t3, t4, t7 tags in their fusion description column, but I can't find their corresponding meaning in the manual on github.

What do these tags mean?

@ndaniel Can you take a look at this question? I am also curious about it. Thank you! Best, xiucz

Commenting to keep this open, because I have the same question and still can't find anything to explain it. I have everything from t1 to t17. I've noticed that the same fusion (if it appears multiple times) has the same t#.
