Automatic Assembly For The Fungi (AAFTF) pipeline

Source:

GitHub - stajichlab/AAFTF: Automatic Assembly For The Fungi

Goal:

• Assemble the genome of two M. alpina strains (Mortierella alpina and Mortierella sp.) sequenced at QUT.

• Identify DAG (Diacyl-glycerol) and Phopholipase (PLA, PLB, PLC and/or PLD) genes

Method

De novo genome assembly of yeast genomes using the AAFTF pipeline. More information:

 (pending) FunGAP pipeline for yeast genome annotation:

Methodology

1. Installing tools and dependencies

Create a conda environment called ‘aaftf’ and install several tools needed by the workflow:

Activate the conda environment:

Install the aaftf pipeline as follows:

To deactivate the environment do:

2. Running AAFTF pipeline

To run jobs on the HPC, we use PBS Pro submission scripts that will submit jobs to an scheduler that will then send jobs to the queue. Use the PBS Pro script below to run 1) quality trimming and filtering; 2) de novo assembly; and 3) check contaminant sequences using the AAFTF pipeline:

The above template is to run the AAFTF pipeline for the Mort strain, to use it for the Alpine strain we need to modify the following two variables in the above script:

Once change the above variables then you can submit the launch_AAFTF_pipeline.pbs script to the scheduler as follows:
