Here, we present a protocol for deriving a continuum score for group 3 and 4 medulloblastoma tumor samples analyzed via RNA-sequencing or DNA methylation microarray. We describe steps for utilizing NMF-defined group 3/group 4 metagenes to calculate a continuum score between 0 and 1 that can be projected onto new sample data analyzed via RNA-sequencing. We then detail procedures for reverse engineering a continuum score for samples analyzed via DNA methylation microarray using a random forest classifier.
在这里，我们提出了一种通过 RNA-seq 或 DNA 甲基化微阵列分析的 3 类和 4 类髓母细胞瘤肿瘤样本进行连续评分的方案。我们描述了利用 NMF 定义的 3 类/4 类混合基因计算 0 到 1 之间连续评分的步骤，该评分可以投射到通过 RNA-seq 分析的新样本数据上。然后，我们详细介绍了使用随机森林分类器为通过 DNA 甲基化微阵列分析的样本反向工程连续评分的过程。
