Are there any tools for discovering tandem repeats around a variant in a VCF file?
After researching a bit, I found a couple of tools that take as input BAM files. I did not test them yet:


GangSTR
lobSTR
hipSTR
Tandem Repeat Finder (thanks to Michael G.'s answer)


If I find more tools, I will update this post. After testing them, I will come back to share my feedback.
