Bash Script Output

Posted on 2012-03-20
Last Modified: 2012-03-21

I currently have a script which ideally, I'd like to run 1000 times by submitting them to a queue on a linux cluster using qsub.

The script is called

I've tried submitting using qsub 10 times from the command line at the same time. All ten scripts fell over, so I suspect each pipeline instance is attempting to access (to write to) the same file somewhere.

I need to try to control where the output goes for each run (for TMP files, and any output files). If the location of where the output goes can't be changed (e.g. if it just gets dumped to the current working directory), would it be possible to create a set of temporary directories? (as part of a bash script).

Here's what I'm thinking:

e.g.  pseudo-code for a control script that submits the jobs to the queue.
runDirs=qw(dir1, dir2, dir3, dir4)
foreach(dir in $runDirs)
       cd $dir
       qsub -cwd -b y -V -q node.q -N name bash
       cd ..

I basically want to submit multiple jobs to a queue without the runs tripping up over one another.

I've attached the scripts which I'm currently working with.

You might try changing
mkdir $TMP

Hi ozo,

Thanks for getting back to me.

mkdir $TMP

This created a TEMP folder for each job in my permanalysis folder i.e. "tmp.17906" etc.

I ran 10 jobs from the commandline at the same time to test your modified code.
Each job failed for different reasons.

cannot find FILE:

formatdb host and controls ...
Run ..

cannot find FILE at /fs/nas15/home/mqbpgsm4/permanalysis/bin/ line 9.
chmod: cannot access `/fs/nas15/home/mqbpgsm4/permanalysis/tmp.8975/': No such file or directory
get molecular mimicry candidates ... line 215: /fs/nas15/home/mqbpgsm4/permanalysis/tmp.8975/ No such file or directory
cat: /fs/nas15/home/mqbpgsm4/permanalysis/tmp.8975/B_burgdorferi*-in: No such file or directory
cat: /fs/nas15/home/mqbpgsm4/permanalysis/tmp.8975/B_burgdorferi*-out: No such file or directory
grep: /fs/nas15/home/mqbpgsm4/permanalysis/tmp.8975/B_burgdorferi*-peptides: No such file or directory
grep: /fs/nas15/home/mqbpgsm4/permanalysis/tmp.8975/B_burgdorferi*-peptidesincontrol: No such file or directory
clean up tmp ...
Job B_burgdorferi completed...
rm: cannot remove `/fs/nas15/home/mqbpgsm4/permanalysis/data/proteomes/B_burgdorferi.fasta': No such file or directory

is this because the same script (found in /fs/nas15/home/mqbpgsm4/permanalysis/bin/ is currently being run on a different job? Would a temporary folder need to be set up for the /bin/ directory where the scripts are being held or am I understanding this wrong?

No string found in fs/nas15/home/mqbpgsm4/permanalysis/tmp.21749/B_burgdorferi1-finalids :

formatdb host and controls ...
Run ..
get molecular mimicry candidates ...
Working on B_burgdorferi1
Blast against control species
Separate fulllength conserved/nonconserved proteins
Ungapped Blast parasite 14mers against control species
Filter peptides control species
Ungapped Blast against host/vector proteome
Filter peptides host/vector

No string to search with was found in /fs/nas15/home/mqbpgsm4/permanalysis/tmp.21749/B_burgdorferi1-finalids. Nothing to do!

clean up tmp ...

Thanks again,

I think for:

cannot find FILE at /fs/nas15/home/mqbpgsm4/permanalysis/bin/ line 9.

It is because PROTEOMEDIR is currently still assigned as a global folder used by all jobs, but it will need to be job specific:

if [ -z "$PROTEOMEDIR" ]

Shuffleseq needs to pick up Original.fasta from the PROTEOMEDIR shown above. BUT it needs to output (-outseq) the file into the specific job folder (this can be the TMP folder created for the job as specified above).
Phobius needs to pick up $PARASITE.fasta from the jobs tmp folder (where it was submitted by Shuffleseq) and it's output should go back in to the jobs specific tmp folder.

How the code looks at the moment:

echo Use shuffleseq to create shuffled proteome
$SHUFFLESEQ -sequence $PROTEOMEDIR/Original.fasta -outseq $PROTEOMEDIR/B_burgdorferi.fasta
echo Run phobius ...

How I think it should look (apologies for any mistakes):

echo Use shuffleseq to create shuffled proteome
$SHUFFLESEQ -sequence $PROTEOMEDIR/Original.fasta -outseq $TMP/B_burgdorferi.fasta
echo Run phobius ...
$PHOBIUSBIN -short $TMP/$PARASITE.fasta > $TMP/$PARASITE.phobius

Would this work? I'm trying to keep everythinbg 'job specific' so that if the same script was run multiple times, there wouldn't be any problem. As it is at the moment I can see many B_Burgdorferi files being created ($SHUFFLESEQ -sequence $PROTEOMEDIR/Original.fasta -outseq $PROTEOMEDIR/B_burgdorferi.fasta) in PROTEOMEDIR=~/permanalysis/data/proteomes

Thanks again,

Solved the immediate problem I had, but this in turn led to another problem.
