Bayesian transcriptome assembly

Download this project as a .zip file Download this project as a tar.gz file

The Bayesembler is a Bayesian method for doing transcriptome assembly from RNA-seq data.


In the making

We are currently working on implementing the following features:

Watch us on GitHub or follow us on Twitter (@bayesembler) to stay informed. Please use the GitHub issue tracking system to request any features you would like us to implement.

Installing the Bayesembler

The Bayesembler runs on both Linux and OS X and is freely available under the MIT License. Static Linux x86_64 builds are available under releases (latest release). Please check out the installation-wiki for further information including how to build the Bayesembler from source.

Running the Bayesembler


The Bayesembler requires paired-end RNA-seq data mapped using TopHat2.


The Bayesembler can be invoked with default settings using

bayesembler -b <tophat2_map.bam>

Important options include:


Assembly in Gene Annotation Format (GTF) as assembly.gtf.

Please consult the manual-wiki for additional options and information about the output.

Bug reports, help and feature requests

We want to know if you are experiencing problems with our program or really need us to implement a new feature. To get in touch with us, please use the GitHub issue tracking system or
