Wrong calculation of FII

[colsen]

Description of the bug

In the documentation on https://nf-co.re/rnafusion/4.0.0/docs/output, the FII is defined as:

Tool Detection (50% of total FII)

Calculated as: (number of tools detecting the fusion) / (number of tools actually used)
This reflects how many of the active tools found the fusion
Database Hits (50% of total FII)

Based on database matches using weights above
Calculated as: (number of database hits) / (total possible database hits)
Final score = (0.5 × Tool Detection Score) + (0.5 × Database Hits Score)

We have a fusion called for which we see in the *fusions.csv file (and also in the report):
LINC00649--MRPS6,FusionGDB2,0.333,0.5 * (2 / 3) + 0.5 * (0.0 / 1)

In my understanding the fusion was found in FusionGDB2 but this was not taken into account for the calculation (database score = 0).

In a different called fusion, we see
JAK3--INSL3,Mitelman,0.417,0.5 * (1 / 3) + 0.5 * (0.5 / 1)

Here the fusion is found in Mitelman -> there the database score > 0.

Do you have any idea what is going on?

Thanks in advance,
Catharina
