retcor.obiwarp(xcms)
retcor.obiwarp()所属R语言包:xcms
Align retention times across samples with Obiwarp
对齐跨越保留与Obiwarp样品时间
译者:生物统计家园网 机器人LoveR
描述----------Description----------
Calculate retention time deviations for each sample. It is based on the code at http://obi-warp.sourceforge.net/. However, this function is able to align multiple samples, by a center-star strategy.
计算每个样品的保留时间偏差。它是基于在http://obi-warp.sourceforge.net/代码。但是,这个功能是能够协调多个样品,由中心明星策略。

参数----------Arguments----------
参数:object
the xcmsSet object
xcmsSet对象
参数:plottype
if deviation plot retention time deviation
如果deviation图的保留时间偏差
参数:profStep
step size (in m/z) to use for profile generation from the raw data files
步长(m / z为)从原始数据文件使用文件生成
参数:center
the index of the sample all others will be aligned to. If center==NULL, the sample with the most peaks is chosen as default.
所有其他指数的样本将对准。如果中心== NULL,默认情况下,被选为最峰的样品。
参数:col
vector of colors for plotting each sample
向量绘图每个样品的颜色
参数:ty
vector of line and point types for plotting each sample
线和点类型的矢量绘制每个样品
参数:response
Responsiveness of warping. 0 will give a linear warp based on start and end points. 100 will use all bijective anchors
响应翘曲。 0会给线性经根据起点和终点。 100将使用双射锚
参数:distFunc
DistFunc function: cor (Pearson's R) or cor_opt (default, calculate only 10% diagonal band of distance matrix, better runtime), cov (covariance), prd (product), euc (Euclidean distance)
DistFunc功能:心病(Pearson的R)或cor_opt(默认情况下,计算距离矩阵,更好的运行时只有10%的斜角带),COV(协),珠三角(产品),EUC(欧氏距离)
参数:gapInit
Penalty for Gap opening, see below
刑罚差距开幕,见下文
参数:gapExtend
Penalty for Gap enlargement, see below
差距扩大的罚款,见下文
参数:factorDiag
Local weighting applied to diagonal moves in alignment.
适用于局部加权对齐对角线移动。
参数:factorGap
Local weighting applied to gap moves in alignment.
当地加权应用对准差距举动。
参数:localAlignment
Local rather than global alignment
地方,而不是全球对齐
参数:initPenalty
Penalty for initiating alignment (for local alignment only) Default: 0
发起对齐的罚款(只为本地对齐)默认:0
值----------Value----------
An xcmsSet object
xcmsSet对象
方法----------Methods----------
retcor(object, method="obiwarp", plottype = c("none", "deviation"), profStep=1, center=NULL, col = NULL, ty = NULL, response=1, distFunc="cor_opt", gapInit=NULL, gapExtend=NULL, factorDiag=2, factorGap=1, localAlignment=0, initPenalty=0)
