Details
详情----------Details----------
The bins are created by computing the proportion of non-spike-in genes with expression values less than or equal to the average expression value at each nominal concentration. Using the default value of cuts, the high bin contains nominal concentrations with 99 percent or more of the non-spike-in expression values lower than it. The medium bin contains nominal concentrations with between 60 and 99 percent of the non-spike-in expression values lower than it. The low bin contains nominal concentrations with less than 60 percent of the non-spike-in expression values lower than it.
创建计算表达式的值小于或等于平均在面值浓度的表达式的值的比例在非尖峰基因的垃圾箱。削减使用默认值,高彬包含面值99%或更多的表达式的值比在非尖峰低浓度。中期bin包含60至99%的非穗表达名义浓度值比它低。低槽包含名义浓度小于60%的表达式的值比在非尖峰低。
