这是我的命令gatk --java-options "-Xmx60g" GenomicsDBImport \
-L chrB6 -L chrB1 -L chrA1 -L chrA4 -L chrA7 -L chrB7 -L chrA2 -L chrB2 -L chrA3 -L chrA5 -L chrB5 -L ScaffoldUN -L chrA6 -L chrB4 -L chrB3 --tmp-dir $tmpdir -R $REF --batch-size 5 \
--reader-threads 5 --max-num-intervals-to-import-in-parallel 5 \
--genomicsdb-workspace-path db --sample-name-map cohort.sample_map
报错是这样的：WARN GenomicsDBImport - GenomicsDBImport cannot use multiple VCF reader threads for initialization when the number of intervals is greater than 1. Falling back to serial VCF reader initialization.
