phylip format using snippy-core with --noref and --aformat=phylip

[FrAoJm]

Hi, I am following this tutorial to produce phylogenetic trees: https://aschuerch.github.io/MolecularEpidemiology_AnalysisWGS/09-SNPphylo/index.html

I used the fastq files of my bacterial isolates using the fast of the original one as a reference genome (fast). I get the tab files, but when I try to perform snippy-core with noref and aformat=phylip I get errors. The first error is saying that I need a reference file. If I try to add the same reference genome I used before, but still wanted to get the phylip format, I get another error saying the fasta is not compatible with the option aformat=phylip.

How can I get the phylip format using snippy-core?

Thank you for your help! Regards
