Contig failing on ctx63 when path colors above 0 used

[er432]

I try running the following:
$MCCORTEX contigs -m 490G -n 12G --colour 1 -p 0:Coelorachis.clean.ctp -p 1:Vossia.k63.clean.ctp refAndSamples.basalAndropogonae.inferredEdges.clean.ctx > Vossia.clean.k63.fa

And I get this:

However, I can successfully run when I only try to get contigs for color 0, as follows:
$MCCORTEX contigs -m 490G -n 12G --ncontigs 1000000 --print --colour 0 -p 0:Coelorachis.clean.ctp refAndSamples.basalAndropogonae.inferredEdges.clean.ctx > Coelorachis.clean.k63.fa

Sorry it took so long to get to this. You should be able to run each sample one at a time:

$MCCORTEX contigs -m 490G -n 12G --ncontigs 1000000 --print --colour 0 -p Coelorachis.clean.ctp refAndSamples.basalAndropogonae.inferredEdges.clean.ctx > Coelorachis.clean.k63.fa

$MCCORTEX contigs -m 490G -n 12G --ncontigs 1000000 --print --colour 1 -p 1:Vossia.k63.clean.ctp refAndSamples.basalAndropogonae.inferredEdges.clean.ctx > Vossia.clean.k63.fa

But it looks like you're hitting a bug. We have had several similar issues so have been rewriting the way we store and represent paths (.ctp files). This work should allow for more flexibility and better interoperability of graph annotations files between programs. The develop branch includes this work which we'll soon make a release for. However this means that the file format for .ctp files has changed and you will need to regenerate them. I'm sorry this has been a hassle for you - McCortex is still under development and your feedback is helpful.
