Making Downloads

Download RNA Baser Sequence Assembler and other free biology tools.

An affordable alternative to the really expensive software for DNA assembly and alignment.



RNA Baser Sequence Assembler is easy to use software for RNA sequence assembly, RNA sequence analysis, contig editing, metadata integration and mutation detection.

While other similar products force you to provide your personal data so they can track you down, send you spam or make promotional phone calls, we offer you instant and unconditioned access to the download link.

Fully functional trial

Trial version is functional. RNA Baser Sequence Assembler is the only software on the market that allows you to save your work while you are in the trial period.

Even after the trial period ends, you can still use RNA Baser's internal tools to edit and view chromatogram files, cut primers, to assemble contigs, reverse complement sequences, etc, but you won't be able to save the contig. If the trial period was not enough for you, you can ask a (free) trial extension key.

Note: Starting with January 2010, all functions available in RNA Baser have been integrated in DNA Baser also. We recommend you to download DNA Baser instead of RNA Baser.

RNA Sequence alignment and RNA sequence metadata integration software

RNA Baser Sequence Aligner

Easy contextual metadata integration: 

RNA Baser Sequence Aligner represents an extension of DNA Baser Sequence Aligner, specialized in processing rRNA sequences. It is optimized for early integration of contextual metadata. This way, the metadata will stay attached to the primary sequence information throughout the complete workflow of sequence analysis, until final submission. In addition, RNA Baser Sequence Aligner is optimized for data exchange with standard non-commercial software used for rRNA sequence analysis and submission.

This is a joint project of HeracleSoftware, Ribocon GmbH and Max Planck Institute for Marine Microbiology in Bremen, Germany

How are we helping you to analyze your rRNA sequences faster?

1. RNA Baser Sequence Aligner is performing for you all the tedious steps in Sequence alignment:

Automatic bad end trimming.

Automatic ambiguous bases correction - More than 98% of ambiguities/mismatches are automatically corrected by RNA Baser without any user input.

Automatic vector removal.

2. State of art graphic user interface designed with one purpose in mind: to minimize the user input:

Access with one single look to all needed data.

None of the necessary functions are far than two mouse clicks.

Synchronized display of the contig map, contig alignment and chromatograms.

Fast navigation between one ambiguous bases.

3. Assemble thousands of DNA/RNA sample files in minutes at batch:

Additionally to the classic single contig assembly mode, RNA Baser offers the possibility to assemble thousands of contigs (clone libraries) in batch mode with a single mouse click.

4. Fast integration of metadata in the sequence information:

Keep sequence and environmental parameters information together; in this way, you will always know were your sequence is coming from

Fast submission to the databases of all relevant data.

With RNA Baser , you can:

Assemble or align to a reference sequence.

Batch assemble or align in groups of sequences by name.

Automatically end clip.

Automatically trim vector sequences.

Import sequences from ABI, SCF, FASTA and SEQ.

View and edit sequence traces.

Mark specific regions (like discrepancies, low-quality areas in chromatograms) with visible colors and quickly navigate to these regions.

Convert between different file formats (ABI,SCF, FASTA, multi-Fasta...).
