译者:生物统计家园网 机器人LoveR
描述----------Description----------
Protein sequences are coded based on their hydrophobicity.
基于其疏水性,编码的蛋白质序列。
用法----------Usage----------
featureHydro(seq,hydro.method="SARAH1")
featureACH(seq,hydro.index="hydroE")
参数----------Arguments----------
参数:seq
a string vector for the protein, DNA, or RNA sequences.
为蛋白质,DNA或RNA序列的字符串向量。
参数:hydro.method
a string for the method of coding protein hydrophobic effect. This must be one of the strings "kpm" or "SARAH1".
一串编码蛋白质的疏水作用的方法。这必须是一个字符串“KPM”或“SARAH1”。
参数:hydro.index
a string for the method of coding protein hydrophobic effect. This must be one of the strings "hydroE", "hydroF" or "hydroC".
一串编码蛋白质的疏水作用的方法。这必须是字符串“hydroE”,“hydroF”或“hydroC”之一。
Details
详情----------Details----------
featureHydro returns a matrix measuring the hydrophobic effect. Parameter "hydro.method" supported following coding methods: "kpm": use a numeral to indicating the hydrophobic effect of amino acid. Each sequence is coded by a N dimension numeric vector. "SARAH1": use a 5 dimension 0-1 vector to indicating the hydrophobic effect of amino acid. Each sequence is coded by a 5*N dimension 0-1 vector.
featureHydro返回一个矩阵测量的疏水作用。参数“hydro.method”支持下面的编码方法:“KPM”:用一个数字来表明氨基酸的疏水作用。每个序列编码一个N维数字向量。 “SARAH1”:用5维0-1向量表明氨基酸的疏水作用。每个序列编码由5 * N维0-1向量。
featureACH returns a matrix with (N-1)/2 columns. N is the length of input sequence, andis N must be odd. Central residue of all windows are the central residue of input sequence. Each column is the average cumulative hydrophobicity over a sliding window.
featureACH返回一个矩阵(N - 1)/ 2列。 N是输入序列的长度,andis N必须是奇数。中央残留的所有窗口的输入序列的中央残留。每一列是通过滑动窗口累积平均疏水性。
