I am building a tool with graphical interface that will convert SFF to FASTQ and multifasta.Last edited by create.share; 06-03-2014, 01:11 AM. -
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.Originally posted by maasha View PostLeave a comment:

Using Biopieces you can do:
orCode:read_sff -i data.sff | write_fastq -o data.fq -x
or both in one go:Code:read_sff -i data.sff | write_454 -o data.fna -q data.fna.qual -x
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.Leave a comment:

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.Leave a comment:

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

I've converted sff to fastq using sffinfo to generate the fasta and qual files. You can then combine them using the perl script on this page

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

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.Leave a comment:

How to convert from sff to fasta or fastq
I have sff files from 454 sequencing. How do I convert sff to fasta or fastq format?

The introduction of single-cell sequencing has advanced the ability to study cell-to-cell heterogeneity. Its use has improved our understanding of somatic mutations1, cell lineages2, cellular diversity and regulation3, and development in multicellular organisms4. Single-cell sequencing encompasses hundreds of techniques with different approaches to studying the genomes, transcriptomes, epigenomes, and other omics of individual cells. The analysis of single-cell sequencing data i

Single-cell sequencing is a technique used to investigate the genome, transcriptome, epigenome, and other omics of individual cells using high-throughput sequencing. This technology has provided many scientific breakthroughs and continues to be applied across many fields, including microbiology, oncology, immunology, neurobiology, precision medicine, and stem cell research.
The advancement of single-cell sequencing began in 2009 when Tang et al. investigated the single-cell transcriptomes...01-09-2023, 03:10 PM -
Element Biosciences made its sequencing market debut this year when it released AVITI, its first sequencer. The AVITI System uses avidity sequencing, a novel sequencing chemistry that delivers higher quality data, decreases cycle times, and requires lower reagent concentrations. This new instrument reportedly features lower operating and start-up costs while maintaining quality sequencing.
