Gedmatch提示未檢出數(shù)量異常地高，錯(cuò)配機(jī)率高？
剛出爐的數(shù)據(jù)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(shù)量異常地高，錯(cuò)配機(jī)率高，請(qǐng)問(wèn)這正常嗎~ 不是說(shuō)有60萬(wàn)個(gè)位點(diǎn)嗎？少了16萬(wàn)個(gè)點(diǎn)~

No call rate一般和DNA的質(zhì)量有很大關(guān)系。No-calls = 13966 = 3.1966490804427 percent. 還好，說(shuō)明您的數(shù)據(jù)沒(méi)有什么大問(wèn)題，在ftDNA這個(gè)rate也會(huì)有不少是在3%左右，不會(huì)對(duì)后續(xù)分析有影響，請(qǐng)放心。
