Thanks thach for the response. Of course they are important informations of the vcf file, but Mutserve also outputs a txt file, which is then annotated by Mutserve Annotate. In such file, there are fields like: Maplocus, OXPHOS_complex, NuMTs_dayama, DuplSeq_rCRS and many others. Do you know any resource from which one can retrieve information about those fields? Thanks

I used the same v2.0.0-rc13 version. The fields that you list come from Mutserve call. The next step (Mutserve annotate) adds basic annotation to the Mutserve call output from the "rCRS_annotation_2020_08-20.txt" file, which contains additional fields, such the ones I listed before.
