makePosFreqCon()所属R语言包:cosmo
Constructing a nucleotide frequency constraint
构建核苷酸频率约束
译者:生物统计家园网 机器人LoveR
描述----------Description----------
This function constructs a posFreqCon object representing a constraint on the unknown position weight matrix that requires the frequency of a given nucleotide to be above a given lower bound, either at a single position in a given interval, or on average across the entire interval
这个函数构造一个posFreqCon对象代表一个未知的,需要一个特定核苷酸的频率,是一座横跨于给定的下限,在一个给定的时间间隔的单一位置,或平均位置权重矩阵约束整个区间
用法----------Usage----------
makePosFreqCon(pos, nuc, lower)
参数----------Arguments----------
参数:pos
This is either the string avg, indicating that the average nucleotide frequency across the interval is bounded from below, or a position in the interval, indicating the nucleotide frequency at that position in the interval is bounded from below.
这可以是字符串avg,表明整个区间核苷酸的平均频率从以下范围内,或在区间的位置,这表明,在间隔位置的核苷酸频率从下面界。
参数:nuc
character This is one of A, C, G, T, GC, AT.
character这是一个A,C,G,T,GC,AT。
参数:lower
numeric the lower bound on the nucleotide frequency of interest
numeric下界利益的核苷酸频率
值----------Value----------
An object of class posFreqCon.
对象类posFreqCon。
