線蟲c-p值及相關(guān)指數(shù)計算
|
|
誰有線蟲每個屬的c-p值的數(shù)據(jù)呢?以及線蟲專有指數(shù)的計算公式中 e, b ,s 是什么意思,怎么計算出來的,ke、kb、ks每個屬是多少,怎么查到?ne、nb、ns怎么計算? 富集指數(shù)EI,(EI,Enrichment Index),EI = 100 × e/(e + b), 基礎(chǔ)指數(shù)BI:(BI,Basal Index),BI = 100 × b/(b + e + s), 結(jié)構(gòu)指數(shù)SI:(SI,Structure Index),SI = 100 × s/(b + s), 通道指數(shù)CI:CI,Channel Index),CI = 100 × 0.8 × Fu2/(3.2 × Ba1 + 0.8 × Fu2), 其中Ba1是c-p值是1的食細菌線蟲的豐度, Fu2是c-p值是2的食真菌線蟲的豐度。 E=∑ke×ne;B=∑kb×nb; S=∑ks×ns。 ke、kb、ks代表各營養(yǎng)類群的賦值(在0.8-5.0之間), ne、nb、ns代表各類群的豐度。 本人剛開始學(xué)習(xí)線蟲,啥也不知道 希望有明白的,能夠詳細的告訴我,非常感謝! |
