详情----------Details----------
Khan et al., 2001 used cDNA microarrays containing 6567 clones of which 3789 were known genes and 2778 were ESTs to study the expression of genes in of four types of small round blue cell tumours of childhood (SRBCT). These were neuroblastoma (NB), rhabdomyosarcoma (RMS), Burkitt lymphoma, a subset of non-Hodgkin lymphoma (BL), and the Ewing family of tumours (EWS). Gene expression profiles from both tumour biopsy and cell line samples were obtained and are contained in this dataset. The dataset downloaded from the website contained the filtered dataset of 2308 gene expression profiles as described by Khan et al., 2001. This dataset is available from the http://bioinf.ucd.ie/people/aedin/R/.
汗等,2001中使用含有6567这3789个已知基因和2778克隆的cDNA微阵列无害环境技术的研究在四种类型童年的小圆蓝单元瘤(SRBCT)基因的表达。这些神经母单元瘤(NB),横纹肌肉瘤(RMS),Burkitt淋巴瘤,非霍奇金淋巴瘤(BL)的一个子集,和尤因家庭肿瘤(EWS),。获得肿瘤活检和单元样本的基因表达谱,并在本集所载。从网站上下载的数据集包含2308基因表达谱的筛选集汗等人,2001年。本集是从http://bioinf.ucd.ie/people/aedin/R/。
In order to reduce the size of the MADE4 package, and produce small example datasets, the top 50 genes from the ends of 3 axes following bga were selected. This produced a reduced datasets of 306 genes.
为了减少的MADE4包的大小,并产生3轴bga选择完小的数据集,例如前50个基因。这306个基因产生减少数据集。
