Denovo, Stacks: Getting an “ambiguous redirect” error I tried running the following command
/public/home/WHC_BBT/Softwares/bin/bin/denovo_map.pl --samples $RawData -O $Popmap -o $fullM2n3 -M 2 -n 3 -m 3 -T 15 &amp;&gt; $logfile

This is the error I got

/opt/gridview//pbs/dispatcher/mom_priv/jobs/14923.admin.SC: line 6:
$logfile: ambiguous redirect

I need help on how to resolve this.
Thanks.
This most likely means your variable $logfile does not exist.
