parallel program for running a command for several files
Hi I have a command to run a module in software Homer the command is the following
findMotifsGenome.pl ERCreInput mm10 motifs/instance/ -find motifs/motif1.motif > motifs/instance/motif1.motif.txt
I want to run the above command using parallel program for several files that are contained in folder motifs/. The files are starting with names motif1.motif and so on. I want to output the files in motifs/instance/motif1.motif.txt. I tried out the following
parallel 'findMotifsGenome.pl ERCreInput mm10 motifs/instance/ -find motifs/{} > motifs/instance/{.}.txt' ::: *.motif
Somehow it is not working can anyone please give me suggestion how correct the code so that it works

Does it throw an error message or just fails? make sure you use parallel correctly, there are several versions with different usage
Type parallel --version and check that you are using GNU parallel by Ole Tange. You should get something like this:
Otherwise you are using the bash parallel command from moreutils, which has a different syntax.
Can you type the following:
GNU parallel 20160422 Copyright (C) 2007,2008,2009,2010,2011,2012,2013,2014,2015,2016 Ole Tange and Free Software Foundation, Inc.

When using programs that use GNU Parallel to process data for publication please cite as described in 'parallel --citation'.
So in my case i am getting the following error Reading input files... 11466 total sequences read !!! Couldn't open motif file: motifs/*.motif !!! Finding instances of 0 motif(s) so somehow the motifs file are not detected using the above command
It looks like you are not in the correct folder? Parallel is replacing {} with *.motif because there aren't any files in your current folder that matches *.motif.
