Details
详情----------Details----------
Batch script for annotation of an (grouped) xcmsSet xs. Generates an xsAnnotate object by calling all involved functions for the annotation step. Function list: 1: groupFWHM() , 2: findIsotopes() , 3: groupCorr(), 4: findAdducts() Return the xsAnnotate object, which inherits all annotations. For more information about the parameters see the specific function manpages.
批处理脚本注释(分组)xcmsSetxs。通过调用注解一步都涉及到功能产生xsAnnotate对象。功能列表:1:groupFWHM(),2:findIsotopes(),3:groupCorr(),4:findAdducts()返回的xsAnnotate对象,它继承了所有注释。如需有关参数,请参阅特定功能的联机帮助页。
值----------Value----------
annotate returns an xsAnnotate object. For more information about the xsAnnotate object see xsAnnotate-class.
annotate返回xsAnnotate的对象。为有关xsAnnotate对象的更多信息,请参阅xsAnnotate级。
