Flexbar preprocesses high-throughput sequencing data efficiently. It demultiplexes barcoded runs and removes adapter sequences. Moreover, trimming and filtering features are provided. Flexbar increases read mapping rates and improves genome and transcriptome assemblies. It supports next-generation sequencing data in fasta and fastq format, e.g. from Illumina and the Roche 454 platform.

Flexbar moved to SeqAn applications: https://github.com/seqan/flexbar
- Demultiplexing of barcoded sequencing runs
- Detection and removal of adapter sequences
- Exact global alignment with free end-gaps
- Paired reads and separate barcode reads
- Galaxy tool definition available in Tool Shed
- Multithreaded computation using TBB library
- Sequence analysis based on SeqAn library
Thanks for Flexbar, it's perfect!
does what it says. fast
Hi aue0618! Yes you are right - there was a bug introduced that got fixed in the latest version! Thanks for the hint- just download 2.13 and it should work again!
theflexibleadap works perfectly.
I like your program, but the reporting of the stats is a little confusing for Pair end data. It is not easy to understand how many PAIRS you have removed based on it not passing one of the filters. If one of the pairs contains an N, you report 1 read (of two total) containing an N, but you also remove the other reads (as you should) but you don't report this number. So if BOTH reads contained the N, you ALSO report 1 for the Discard N but still only remove 1 read pair....Even though there are 2 reads with an N Also, it seems that the USED field is always the same as the READS IN FILE field...I would have expected the USED field to be READS IN FILE minus DISCARD_B minus DISCARD_QUAL Or am I missing something ?
