Versions
poppunk 2.4.0

Command used and output returned
Taking the listeria example dataset mentioned on Quickstart in 2.2.0 docs (https://poppunk.readthedocs.io/en/v2.2.0-docs/quickstart.html):
poppunk --create-db --r-files reference_list.txt --output lm_example

poppunk_visualise --ref-db lm_example --model-dir modelK4 --output Try01 --cytoscape

Describe the bug

Hello! Here's the cytoscape bug I mentioned in the other issue

I can't generate a cytoscape output, whenever I try with --cytoscape flag I get:

Graph-tools OpenMP parallelisation enabled: with 1 threads
PopPUNK: visualise
Loading BGMM 2D Gaussian model
Completed model loading

OSError: error reading from file '':basic_ios::clear: iostream error

A folder is created, however it is empty
I was able create a microreact output, it seems to be a cystoscape-only probem

Maybe useful information:
I'm using poppunk in WSL

Hi @andreaniml - does the version you are using have a --network-file option? That has been added in recent versions to enable different types of file to be visualised with cytoscape. If you use this to specify the path to the graph file (e.g. --network-file modelK4/modelK4_graph.gt) that should hopefully generate the output you want.

[andreaniml]

It worked! Thank you!

Just to check, here the names of the nodes are imported as "n0, n1, n2" instead of the sample names (those on "id")

This is normal behavior, right? (I'm sorry for the silly question, I never used cytoscape)

[nickjcroucher]

Yes, this is the expected format for outputs to Cytoscape - we'll update the tutorial accordingly.

Closing as this will be addressed in #185
