Talk about scRNA-seq memory usage and rm() #250

Open jashapiro opened 4 years ago

jashapiro commented 4 years ago

The current scRNA-seq notebook 01 starts to get into pretty high memory usage of ~4Gb with multiple copies of the large count matrix under different filtering conditions, etc. It might be good to add a section about keeping that usage down through judicious use of rm() to clear out earlier steps in the pathway. Also a note that on a personal computer, this could be a real limitation.

This may not have made it in explicitly for July 2020, so I am keeping it in as a future update.
