Hi all, I'm actually trying to assemble a lepidopteran genome (around 1.5 GB) using IDBA-1.1.1 So I cleaned my reads and now I need to assemble my genome. To do so I used this script:

#PBS -S /bin/bash
#PBS -l nodes=1:ppn=16,mem=800gb

# sample name
NAME=ACG-006

# location of IDBA
IDBA='/panhome/TOOLS/idba-1.1.1/' 

INPUT1='/pandata/LEPIWASP/ACG-0006_0027/ACG-006/'$NAME
'_reads1.fq'
INPUT2='/pandata/LEPIWASP/ACG-0006_0027/ACG-006/'$NAME
'_reads2.fq'


###################################################################################
#       assemble
###################################################################################


# run the assembly :
echo 'start assembly' $(date)

$IDBA'bin/idba_ud' -o /pandata/LEPIWASP/ACG-0006_0027/OUT-0006-2 -r $INPUT1'.fa' --num_threads 8

echo 'fin assembly' $(date)

But it seems that it did not work because I did not get any scaffold.fa file as expected.

Here is the log content: bguinet@pbil-deb:/pandata/LEPIWASP/ACG-0006_0027/OUT-0006-2$ more log
