Hey anyone who contributed to salsa2 (@astrovsky01 @bgruening @gallardoalba and @Delphine-L ) . I could need some help here.

Seems that the test data used here does not fit (there is a Traceback when reading the bed file complaining about chr1 .. which was ignored without agressive `). I guess ids do not match. Has anyone an idea how we could get a working test?
