General info

TransPi – a comprehensive TRanscriptome ANalysiS PIpeline for de novo transcriptome assembly

TransPi is based on the scientific workflow manager Nextflow. It is designed to help researchers get the best reference transcriptome assembly for their organisms of interest. It performs multiple assemblies with different parameters to then get a non-redundant consensus assembly. It also performs other valuable analyses such as quality assessment of the assembly, BUSCO scores, Transdecoder (ORFs), and gene ontologies (Trinotate), etc. All these with minimum input from the user but without losing the potential of a comprehensive analysis.

Pipeline processes

Figure 1. TransPi v1.0.0 flowchart showing the various steps and analyses it can performed. For simplicity, this diagram does not show all the connections between the processes. Also, it omits other additional options like the BUSCO distribution and transcriptome filtering with psytrans (see Section 2.6). ORFs=Open reading Frames; HTML=Hypertext Markup Language.

Manual

TransPi documentation and examples can be found here

Publication

Preprint of TransPi including kmer, reads length, and reads quantities tests can be found here. Also we tested the pipeline with over 45 samples from different phyla.

TransPi has been peer-reviewed and recommended by Peer Community In Genomics (https://doi.org/10.24072/pci.genomics.100009)
