输入参数
SequenceMatrix |
一个n-by-25序列信息的完美匹配(PM)探针的序列信息矩阵®转基因®数组,哪里nis the number of probes on the array. Each row corresponds to a probe, and each column corresponds to one of the 25 sequence positions. Nucleotides in the sequences are represented by one of the following integers:
提示 您可以使用 |
mmintenthenty |
Column vector containing mismatch (MM) probe intensities from a CEL file, generated from a single Affymetrix GeneChip array. Each row corresponds to a probe. 提示 您可以从 |
探针值 |
包含探针索引信息的列向量。探针集中的探针编号为0n- 1, wherenis the number of probes in the probe set. 提示 您可以使用 |
Showplotvalue |
控制25个序列位置中每个碱基的每个碱基(a,c,g和t)的亲和力值的显示,以示出Affymetrix Genechip Array上的所有探针。选择是 |
输出参数
affinpm |
根据其探针序列和MM探针强度计算的PM探针亲和力的列矢量。 |
AffinMM |
Column vector of MM probe affinities, computed from their probe sequences and MM probe intensities. |
基础 |
4-by-4 matrix containing the four parameters for a polynomial of degree 3, for each base, A, C, G, and T. Each row corresponds to a base, and each column corresponds to a parameter. These values are estimated from the probe sequences and intensities, and represent all probes on an Affymetrix GeneChip array. |
