Error loading GFA file

[brettChapman]

Hi

I'm trying to load my GFA file, but I'm getting an error.

gfaestus *.smooth.gfa *.smooth.chop.og.lay
loading GFA
loading GFA with 734 nodes, 1003 edges
adding nodes
adding edges
adding paths
created path handles
thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: stream did not contain valid UTF-8', src/main.rs:116:61
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

echo $RUST_BACKTRACE
1 

I've also set the environment variable RUST_BACKTRACE=1 but still get no more information about the error.

I'm trying to visualise graphs produced from PGGB (https://github.com/pangenome/pggb). At the moment I'm only looking at small graphs representing a gene region. Thanks for any help you can provide.

You need to have odgi output the layout file in TSV format (I think it's the -T command line flag) // Christian

Thanks. I managed to generate a TSV formatted layout file.

After running I now get a different error message:

If you're on Mac, you need to have MoltenVK installed https://github.com/KhronosGroup/MoltenVK // Christian

Hi, I've been trying to get the MoltenVK libraries installed on my Mac with no success. It doesn't look very straight forward to install the libraries.

I've tried:

xcodebuild build -quiet -project MoltenVKPackaging.xcodeproj -scheme "MoltenVK Package (macOS only)" -configuration "Debug"

And then running gfaestus again, but I still get the same error about loading libvulkan.1.dylib.

My MacBook Pro is running Catalina 10.15.7.

Is there a more straight forward way to install, perhaps through homebrew or similar? Thanks.

[brettChapman]

I realised I hadn't installed dependencies. So I tried this:

./fetchDependencies --macos
sudo make macos
sudo make install

I still get the same error about libvulkan.1.dylib image not found.

I have a similar problem with today's master, rust 1.51.0 and Archlinux:

gfaestus cerevisiae.pan.fa.aed9ce4.34ee7b1.891e76b.smooth.gfa cerevisiae.pan.fa.aed9ce4.34ee7b1.891e76b.smooth.og.lay.tsv

Currently happening with all data sets I tried. Happy to share if you need some.

I don't have a Mac, so I can't really help. I'd suggest trying another Vulkan app (these examples are easy to build: https://github.com/SaschaWillems/Vulkan); if they work, there's probably something wrong with gfaestus

I think it's because it needs the Vulkan SDK, I'd accidentally set it up so even release builds use the debug features from the SDK.

Latest master should work without the SDK (though you may still need it to compile the shaders)

Got it. Now it works for me, thank you very much @chfi !
