      maxnrec = 1e+05
    )

### Arguments

`bq` | bigrquery BigQueryConnection instance
`basicfilt` | a dplyr::filter instance or NULL to convert entire MAF

         aut = as.character(1:22) # some records in BQ have missing Chromosome
         chk = mc3toGR(con, basicfilt=function(data) dplyr::filter(data,
              project_short_name=="TCGA-BRCA",
              SYMBOL=="TP53", Chromosome %in% aut))
         print(chk[,1:5]) # lots of mcol fields
