    I am building a tool with graphical interface that will convert SFF to FASTQ and multifasta.

    Thank you - discovered Biopieces because of this post and, after some mucking around with macports and ruby installations on OSX, finally got it working. THANK YOU. Very handy set up tools.

    Using Biopieces you can do:

    Code:
    read_sff -i data.sff | write_fastq -o data.fq -x
    or

    Code:
    read_sff -i data.sff | write_454 -o data.fna -q data.fna.qual -x
    or both in one go:

    Code:
    read_sff -i data.sff | write_fastq -o data.fq | write_454 -o data.fna -q data.fna.qual -x

    this program works very well for converting directly from sff to fastq

    I don't think sff_extract can do this (yet). Assuming you are using the standard Roche 454 MID barcodes, then Roche's sfffile from their "off instrument applications" package would be the easiest way to do this.

    Does this sff_extract can handle multiplex files? I have 48individuals/run on a Roche 454 junior and I would like to demultiplex the sff files.

    Thanks.

    You can simply type the command below and it will generate 3 files, .fasta, .fasta.qual, .xml, for you.

    sff_extract XXX.sff

    "sff_extract -Q" seems easier in handling :-)

    to combine them into Sanger fastq. Your fasta and qual files should have the same basename for it to work.

    Yes, both sffinfo from Roche and the free open source options of sff_extract and Biopython were mentioned in the thread Chris linked to:

    There is a roche script called "sffinfo", which takes and sff file and generate a fasta file.
