scanpy的标准化从sc.pp.normalize_per_cell()更新成了sc.pp.normalize_total(),它官方也是建议用后者(当然前面这个函数仍然存在,且可以正常使用)。二者目的是基本一致的,处理数据的过程也没变,但是存在细微的差别,总体而言就是新的sc.pp.normalize_total()在参数设置方面更加人性化了。如下是旧的sc.pp.normalize_...
equal to the median of total counts for observations (cells) before normalization. 如果为None,将每个cell的library size归一化到中值,此中值是指所有cells的library size的中值。 如在上例中,所有cell的library size向量为: array([21., 7., 28.], dtype=float32) 那么中值为21,归一化后,所有cell的libr...

Subsequently, we normalize the data to a library size of 10,000 per cell and apply a log1p transformation. Low-quality samples with fewer than 1000 cells are removed, with an exception made for the hamster dataset to preserve an adequate sample size. The data matrix is then refined to ...
