Hi @lmanchon, I believe it is not just VarDict issue. There is a difference between contig names used in both VCF files, please check that you used the same references for both of them.

right, i use recalibrated bam for Mutect2 and not recalibrated bam for Vardict.
Do you think it's necessary to recalibrate bam file for Vardict ?
