error while running ppanggolin workflow --fasta testingDataset/organisms.fasta.list command. about ppanggolin HOT 3 CLOSED

Hi,

The tool looks for them in the working directory, so if the files are not in 'FASTA/' where you execute PPanGGOLiN, it will not find them. Looking at where you are executing PPanGGOLiN, they are in testingDataset/FASTA/.

If you put yourself in 'testingDataset/' and then run 'ppanggolin workflow --fasta organisms.fasta.list' it should work nicely.

For your personnal usage, using absolute paths in the 'organisms.fasta.list' file is probably better, this is what I usually do with my own data.

Thank you @axbazin for your prompt response, now it works well. I have another query, Is it possible to work on viral pangenome analysis with this ppanggolin tool?

Great !

Originally it was designed for Archaea and Bacteria only, but another group managed to reconstruct pangenomes of phages / plasmids with PPanGGOLiN (see https://www.biorxiv.org/content/10.1101/2020.11.09.375378v1 ), so it is possible.

Beware however that the annotation tool used by ppanggolin is prodigal, so it may not be adapted to viruses and you might want to use your own annotations (--anno option rather than --fasta option for the input files, and using gff or gbff files instead of fasta files)
And parameters were chosen for bacterial species pangenomes so you might want to adapt the parameters as well, however I lack knowledge in viral genomics to know what would or would not be good there.
