Details
详情----------Details----------
Batch script wrapper for combining the annotation and the diffreport for a (grouped) xcmsSet xs. Function list: 1: diffreport(), 2: groupFWHM(), 3: findIsotopes(), 4: groupCorr(), 5: findAdducts() For a speedup calculation users can create a quick run, with quick = TRUE to preselect pseudospectra of interest. The indices of those pseudospectra are set with psg_list in a second run. On the other hand, a automatic selection with pval_th and/or fc_th can be performed. Returns the normal xcms diffreport table, with the additional CAMERA slots
结合注释和(分组)xcmsSetxsdiffreport批处理脚本包装。功能列表:1:diffreport(),2:groupFWHM(),3:findIsotopes(),4:groupCorr(),5:findAdducts(对于加速计算用户)可以创建一个快速运行,快速= TRUE预选伪谱利益。这些伪谱指数在第二次运行psg_list。另一方面,可以进行自动选择与pval_th和/或fc_th的。返回正常xcms diffreport的表,额外的相机插槽
值----------Value----------
annotateDiffreport returns an diffreport, see diffreport, within additional columns containing the annotation results.
annotateDiffreport返回一个diffreport,看到diffreport内额外的列包含注释的结果。

#Multiple sample [多个样品]
library(CAMERA)
library(faahKO)
xs.grp <- group(faahko)
xs.fill <- fillPeaks(xs.grp)
#fast preselection[快速预选]
# diffreport <- annotateDiffreport(xs.fill,quick=TRUE)[< - annotateDiffreport diffreport(xs.fill,快速= TRUE)]
# index <- c(1,18,35,45,56) #Make only for those grps a adduct annotation[指数< - C(1,18,35,45,56)#只对那些GRPS 1加合物的注解]
# diffreport2 <- annotateDiffreport(xs.fill,psg_list=index,metlin = TRUE)[diffreport2 < - annotateDiffreport(xs.fill,psg_list =指数,METLIN = TRUE)]
#automatic selection for groups with peaks p-val < 0.05 and fold-change > 3[自动选择与峰组的P-值<0.05倍变化> 3]
# diffreport <- annotateDiffreport(xs.fill,pval_th=0.05,fc=3)[< - annotateDiffreport diffreport(xs.fill,pval_th = 0.05,FC = 3)]
