I'm trying to use cd-hit to generate a 0.9 sequence identity cutoff of the Blast NR database.
Here's what I'm running:
cd-hit -i nr -o nr90 -c 0.9 -M 1000
But, even though I'm using the
-M 1000 option, the command just gradually uses up all the available RAM (8gb) and then crashes. Any idea on how to fix this?
