Hello, I'm trying to run the code on the attached file (file extension .txt because .fna is not allowed on Github). I'm getting the following error:

The ulimit for the number of open files is set to unlimited:

niklas@phoenix:~/code/ggcat$ ulimit
unlimited

coli3.txt

Hi Jarno, on my machine processing the file requires a file ulimit of about 5150. I already set the soft ulimit in the code to match the hard ulimit of the system, what's the output of ulimit -Hn?

I see, my bad. The output of ulimit -Hn is 4096.
