Gedmatch提示未檢出數量異常地高，錯配機率高？
剛出爐的數據上傳到Gedmatch獲得此提示：
?
Number of SNPs utilized by GEDmatch template = 436895
Number of regular SNPs = 422547
Heterozygosity index = 0.27308621064558 (fraction of total SNPs that are heterozygous)
No-calls = 13966 = 3.1966490804427 percent.
This kit has an unusually high number of no-calls, which usually results in a larger number of false matches.

Gedmatch提示未檢出數量異常地高，錯配機率高，請問這正常嗎~ 不是說有60萬個位點嗎？少了16萬個點~

No call rate一般和DNA的質量有很大關系。No-calls = 13966 = 3.1966490804427 percent. 還好，說明您的數據沒有什么大問題，在ftDNA這個rate也會有不少是在3%左右，不會對后續分析有影響，請放心。
