# Release note 09.15.23

## Recently published apps

We have just published the following tools from the **BBTools 39.01** toolkit:

* **BBDuk**: used for trimming, filtering, and masking of input reads.
* **Reformat**: used for generic read-processing tasks (changing ASCII quality encoding, interleaving, file format, compression).
* **BBMap**: used for splice-aware read alignment.
* **Dedupe**: used for removing duplicates from input sequences.
* **SplitNextera**: used for splitting Nextera long-mate-pair reads.
* **CalcUniqueness**: used for determining library complexity and the need for additional sequencing by generating kmer uniqueness histogram.
* **Taxonomy**: used for printing taxonomy information for provided organism identifiers.
* **Repair**: used to correct disordered reads and reads whose mates have been lost.
* **Seal**: used for alignment-free sequence quantification.
* **BBMerge**: used for merging overlapping paired end reads.
* **BBMask**: used for masking low-complexity, tandem repeats or SAM mapped regions.
* **Tadpole**: used as a kmer-based assembler.
* **Statistics**: used for calculating assembly statistics.
* **BBNorm**: used for normalizing read depth based on kmer counts.
