If you are experiencing issues with Variant Recalibration either in VariantRecalibrator or ApplyVQSR, consider adjusting the max_gaussians. If a dataset gives fewer variants than the expected scale, the number of Gaussians for training should be turned down. Lowering the max-Gaussians forces the program to group variants into a smaller number of clusters, which results in more variants per cluster. - 1. ped file in the input shows the family relationship between samples, the format should be the same as in GATK website [link](https://gatkforums.broadinstitute.org/gatk/discussion/7696/pedigree-ped-files), the Individual ID, Paternal ID and Maternal ID must be the same as in the inputs vcf files header. + 1. ped file in the input shows the family relationship between samples, the format should be the same as in GATK website [link](https://gatk.broadinstitute.org/hc/en-us/articles/360035531972-PED-Pedigree-format), the Individual ID, Paternal ID and Maternal ID must be the same as in the inputs vcf files header. 1.
