I have a feeling the job is hung. Is this under a job scheduler? In my experience, bbduk starts writing output even when running under a scheduler right away.Comment

It was submitted to a server with a scheduler, yes.
It's just odd that it's the exact same code and dataset, but the only difference is hdist=1...same set up with hdist=0 runs fine.Comment

Are you able to ssh to the node this is job is on and see if the bbduk is running (something like top -H)?Comment

The java process (should correspond to bbduk) appears to be sleeping (at least in this screenshot). Does it change back to R periodically or is it staying in S?
@Brian had talked about memory requirements with hdist=1 before. It may not be applicable in your case.Comment
-
Based on a minute of observation, it appears to be sleeping, however the %CPU and %MEM change as I re-issue 'top'.Comment
-
Based on Brian's comments, I bet I have run out of memory. My reference is very large, and a 3*K increase in memory would put me over my server capacity. I will try to re-run with a smaller reference.Comment
-
Unless your scheduler is buffering the entire output in some temp location you should have seen trimmed files right away (have you ever looked before if a job does that)? Did you try top -H to see all ~40 java threads?
Based on your last comment that must be the case.Comment

reads mapped per gene
Hi,
can you suggest how to get raw reads mapped per gene from bbmap?
Thanks,
S.Comment

Based on your other posts you appear to have discovered htseq-count and featureCounts. BBMap suite does not have a read counting program (though @Brian has one on the wishlist of things to add to BBMap).Originally posted by susanklein View PostComment

hi! is there a way to extract specific sequences from fasta file, regarding their positions in the file using BBMap tools? I know the numbers of their name lines and want to extract whole sequences to a file.Comment

It is not clear if you know their identifiers (or just their positions). If you have the identifiers then you can do the followingOriginally posted by JeanLove View Post
Even though this example is for fastq files I am reasonsably certain that it would work for fasta. Make sure your file names end in .fa to facilitate that.By default, "filterbyname" discards reads with names in your name list, and keeps the rest. To include them and discard the others, do this:
Code:$ filterbyname.sh in=003.fastq out=filter003.fq names=names003.txt include=t
In case BBMap does not work you can try faSomeRecords utility from Jim Kent @UCSC which is described here: http://seqanswers.com/forums/showthread.php?t=64004Comment

If you know the sequence numbers, you can use getreads.sh:
Usage: getreads.sh in=<file> id=<number,number,number...> out=<file>
The first read (or pair) has ID 0, the second read (or pair) has ID 1, etc.
Parameters:
in=<file> Specify the input file, or stdin.
out=<file> Specify the output file, or stdout.
id= Comma delimited list of numbers or ranges, in any order.
For example: id=5,93,17-31,8,0,12-13Comment

The immune system’s power comes from its genetic diversity, allowing myriad threats to be neutralized through first recognizing foreign antigens. That diversity is also what makes the immune system so difficult to study. Recent advances in sequencing technology and computational biology, however, are giving researchers new tools to understand immune responses and immune-related diseases in greater detail.
This convergence of genetics, immunology, and computation...09-01-2026, 05:41 AM
