Mykrobe predictor AMR prediction not working

Question

I am getting the following error message when trying to execute AMR prediction on the command line.

mykrobe predict tb_sample_id tb -1 /home/TB/demo_input_file_for_M.tuberculosis_app.fastq

The species chosen was Tuberculosis (TB), whereas the sample data file was pulled down from Mykrobe website ( https://github.com/iqbal-lab/Mykrobe-predictor/releases/download/v0.1.1-beta/demo_input_file_for_M.tuberculosis_app.fastq.gz ).

and the error message I'm getting...

Traceback (most recent call last):

Any suggestions would be appreciated.

Answer 1

The error indicates that mccortex31 is missing.

Did you install it according to the documentation ?

cd Mykrobe-predictor
cd mccortex
make    
export PATH=$PATH:$(pwd)/bin
cd ..

I'm one of the authors of Mykrobe predictor. As someone above commented, probably the right place to ask this question is as a Github issue on our Mykrobe predictor repository:
