    pblat empty output

    Hi,

    I have a single computer with multiple cores, I use pblat at http://icebert.github.io/pblat/

    I got only empty temp files as well as empty outpout

    I really do not understand what is the nature of the problem, I think a memory problem

    I run it like following : nohup `sudo ./Jobs_pblat.sh` &

    the Jobs_pblat.sh contains : $PRGEXEC/pblat -threads=12 -prot -trimT -out=blast9 -minIdentity=25 $DB/db.faa $INFILE/"Orfs.faa" -out=blast9 $RESULTDIR/"Orfs_blat_outblast9_results.out"

    Anybody has the same issue with pblat

    Thanks for reading my thread

    Has this worked before or this is the first time you are using this program?

      Is the first time I used It
      I tried parallel blat (pblat ) and blat, I got the same behaviour

        Can you take a few sequences from each file and run them against each other using blat/pblat to ensure that you have a working program before trying to tackle the full dataset?

        BTW: Why are you adding sudo to your job?

          With a small number of sequences it works fine
          I think my database is huge (38 G) may I have to divide my database into several parts and do several blat

          thanks again for advices

            Or you could reverse the roles and make the database into query.

                Nine Things a Sample Prep Scientist Thinks About Before Sequencing
                by SEQadmin2


                I’m not a sequencing expert. I’m a purification scientist who uses NGS to evaluate workflows my group develops. With this perspective, we think about the sample first and the NGS workflow second. The sequencer is an exceptionally honest reporter, but it can only report on what you give it, so whether you get clean, interpretable data from an NGS workflow is largely determined before you begin.

                Here are nine questions we think about, in roughly the order they matter, before...

                From Collection to Sequencing: Why Sample Preparation and Preservation Define Sequencing Data
                by SEQadmin2


                Data variability is still an issue in sequencing technologies despite the advances in reproducibility and accuracy of these platforms. But the problem does not originate in the sequencing itself, but in the previous steps, before the sample reaches the sequencer.


                The first step is collection, followed by preservation and sample preparation for analysis. Most scientists overlook those steps, but not being careful might just be skewing the experiment’s results.
