After having successfuly installed kraken and jellyfish, I'm trying to build the standard database. I run the following command on a virtual Ubuntu with 102 Go of RAM and 16 cpu :
kraken-build --standard --threads 16 --db $DBNAME
Found jellyfish v1.1.11 Skipping download of bacterial genomes, already downloaded here. Skipping download of viral genomes, already downloaded here. Kraken build set to minimize disk writes. Creating k-mer set (step 1 of 6)... Found jellyfish v1.1.11 Hash size not specified, using '11637743885'
My problem is that the first step is still running after 2 days and seems to never end. It is suppose to take only 10 minutes with 16 threads according to the manual.
Is there someone who have already had this issue and solve it ?
Thanks in advance.
