Sample meta data

meta data associated with each sample, and columns: * **id** - unique ID for sample. Composed of sample number, cell line, and dosage information. * **sample** - sample number. Range from 1-230. Each set of 5 are the treatments for one individual, in increasing concentrations of dox. * **cell_line** - the cell line number. Each cell line corresponds one individual. * **dbgap** - anonymized ID for matching cell_line to genotypes. * **sample_id** - anonymized ID assigned to each unique combination of `dbgap` and `dosage. * **dosage** - the concentration of dox used in the treatment. * **rin** - the RNA Integrity Number (RIN). Range from 1-10. * **rna_conc** - the RNA concentration (ng/uL) after RNA extraction. * **lib_prep_batch** - the batches the libraries were prepared in. * **index** - the TruSeq adapter index used for multiplexing. * **library_conc** - the concentration (ng/uL) of the library measured on the Bioanalyzer. * **fragment_size** - the mean fragment size as measured on the Bioanalyzer. * **qpcr** - the library concentration (nmol) as measured via qPCR. * **qpcr_dilute** - the concentration (nmol) of the diluted library. * **master_mix** - the master mix for pooling libraries. 10 samples (2 individuals) per master mix. * **lane_perc** - The percentage of sequences in one lane that were assigned to a sample.本数据集为每个样本关联元数据，包含以下字段： * **id** - 样本唯一标识符，由样本编号、细胞系及剂量信息组合而成。 * **sample** - 样本编号，取值范围为1~230。每5个样本为一组，对应同一个体的多柔比星（dox）处理组，浓度按梯度递增。 * **cell_line** - 细胞系编号，每个细胞系对应一个独立个体。 * **dbgap** - 用于匹配细胞系与基因型的匿名标识符。 * **sample_id** - 为`dbgap`与`dosage`的每一组唯一组合分配的匿名标识符。 * **dosage** - 样本处理所用的多柔比星（dox）浓度。 * **rin** - RNA完整性数值（RNA Integrity Number, RIN），取值范围为1~10。 * **rna_conc** - RNA提取完成后的RNA浓度，单位为纳克每微升（ng/μL）。 * **lib_prep_batch** - 文库制备批次。 * **index** - 用于多重测序的TruSeq接头索引（TruSeq adapter index）。 * **library_conc** - 经生物分析仪（Bioanalyzer）检测得到的文库浓度，单位为纳克每微升（ng/μL）。 * **fragment_size** - 经生物分析仪（Bioanalyzer）检测得到的平均文库片段长度。 * **qpcr** - 经定量聚合酶链反应（qPCR）检测得到的文库浓度，单位为纳摩尔（nmol）。 * **qpcr_dilute** - 稀释后文库的浓度，单位为纳摩尔（nmol）。 * **master_mix** - 用于文库混合的预混液，每个预混液可容纳10个样本（对应2个独立个体）。 * **lane_perc** - 单条测序 lane 中分配至该样本的序列占比。
