i try to use CREx and CREx2 but I get the “missing header” error. As an input file, I use the file in gene order FASTA format as stated in the readme file on GitHub.
> genome1
A B C D
> genome2
A C B D
> genome3
A -C -B D
> genome4
A -C B D
As a guess, having two words on the > line was likely the problem. I guess you could create a compound word with the >species-name if you want to track that part.
The tool author happens to be a part of the Galaxy community, and follows this forum. Let’s see if they have more to add. Hi @bernt-matthias – can you help? And I’m wondering if we could put an example of the input file directly on the tool form Help as a reference? Thanks!
Dear @jennaj and @bernt-matthias,
it works now. My problem was not only with heading line but also the file format was considered as .txt (not .fasta).
Thank you!
