phyluce_assembly_match_contigs_to_probes - AttributeError: 'NoneType' object has no attribute 'groups'-NEW Issues #337

Closed jjinzhou closed 2 months ago

Dear Professor Faircloth,

I'm having a problem running this command"phyluce_assembly_match_contigs_to_probes", which seems to be the same problem as #233 and #321. I modified the ~/.phyluce.conf in conda environment according to your answers to these two questions, i.e

[headers] trinity:comp\d+_c\d+_seq\d+|c\d+_g\d+_i\d+|TR\d+|c\d+_g\d+_i\d+|TRINITY_DN\d+_c\d+_g\d+i\d+ velvet:node\d+ abyss:node\d+ idba:contig-\d+\d+ spades:NODE_\d+length\d+cov\d+.\d+ minia3:scaffold_\d+uid\d+

I made this change because the assembly software was selected Minia3 and the file starts with scaffold_41_uid_1710815508.But the results still show the same error. I then tried the --regex scaffold_\d+_uid_\d+ parameter, but the results were still wrong.

I don't know what went wrong and I was hoping for your guidance. Here is the code I used, and the specific error

phyluce_assembly_match_contigs_to_probes \ --contigs assemblies_endding \ --probes hymenoptera-v2-PRINCIPAL-bait-set.fasta \ --output uce_extraction \ --min-coverage 67 \ --min-identity 80

The header string you are using looks incorrect. It should be something like:

minia3:scaffold_\d+_uid_\d+

to match a header name like:

scaffold_41_uid_1710815508

The --regex command won't work - that's meant for something else.

Thank you so much for your quick reply! But sorry, I think it was a formatting error caused by pasting. That's exactly the format I'm using. But the mistake still occurs

I'm not sure - Minia is not a supported assembler, so what you are trying to do is non-standard. If I had to guess, it would be that some scaffolds/contigs in the output have a different header format than the one you think they have. But I don't use Minia, so I'm not sure what the header format looks like for all scaffolds/contigs.

Thank you very much for your help. I have re-checked the header format of each sample, and it is indeed the same format. But I didn't have a lot of samples so I decided to reassemble them with spades to avoid this problem. Wish you have a good day!
