<p>Hi all,</p>

<p>Any script available for doing sequence length disrtibution of fastq file?</p>

<p>Thanks,
Deepthi</p>

Another possibility, from BBMap:

    readlength.sh in=reads.fq out=histogram.txt

The default is 10bp bins with a max of 80kbp, but those can be configured (run the shellscript with no arguments for details).  It's very fast, and handles fastq/fasta/sam/bam; raw/gzip/bzip2.
