#This is used in my docker container

##PATH
#DRAP install directory in the Docker container
cd /usr/local/src/drap

#DRAP configuration PATH
cd /usr/local/src/drap/cfg

#Edit configuration (change "local_cpu" and "n_cpu")
vi /usr/local/src/drap/cfg/drap.cfg

#Trimmed and filtered by Kraken2 sequence PATH
cd /mnt/data/pri_data/kraken

##Step 1: merge forward and reverse reads (1 and 2), I use 15 cores here (-j15), you can change it based on your server
cd /mnt/data/pri_data/kraken && pwd && ls
parallel -j15 "zcat {} >> merged_1.fq.gz" ::: *_1.fq.gz
parallel -j15 "zcat {} >> merged_2.fq.gz" ::: *_2.fq.gz

##Step 2: run DRAP for denovo assembly
cd /usr/local/src/drap && pwd && ls

#Write script for further modification (change CPU number for faster speed)
runDrap \

#Edit the CPU number used in tgicl (It always fails when more than 6 cpus are used here). This is a tool used in step 5.
