描述----------Description----------
Protein sequences are coded by pseudo amino acid composiion.
蛋白质序列编码伪氨基酸composiion。
用法----------Usage----------
featurePseudoAAComp(seq,d,w=0.05)
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:d
an integer used as paramter of featurePseudoAAComp (d>=1). Coupling between amino acids X(i) and X(i+d) are considered as features.
整数featurePseudoAAComp(D> = 1)放慢参数作为。 x(i)和x(I + D)为特征的考虑。氨基酸之间的耦合
参数:w
a numeric value for the weight factor of sequence order effect in featurePseudoAAComp.
为featurePseudoAAComp顺序效果的权重因子的数值。
Details
详情----------Details----------
featurePseudoAAComp returns a matrix representing the pseudo amino acid composiion. Each row represented features of one sequence coding by a 20+d dimension numeric vector. The first 20 features indicates the composition of 20 amino acids. The last d features indicates the coupling between amino acids X(i) and X(i+d). Coupling value is cacluated by hydrophobicity, hydrophilicity and mass of amino acids.
featurePseudoAAComp返回一个矩阵代表伪氨基酸composiion的。每一行代表一个序列的功能,通过20 + d维数值向量编码。前20个特征表明20个氨基酸组成。最后的三维特征,表明氨基酸×(I)和X(I + D)之间的耦合。耦合值cacluated氨基酸的疏水性,亲水性和质量。
