Hello,
I am using HUMANN3 and have downloaded it fully and run the example files which have given me outputs. Now I am trying to use it for small fastq file as a test run on my data though am getting the error below:
o species were selected from the prescreen. because of this the custom chocophlan database is empty. this will result in zero species-specific gene families and pathways. running diamond … aligning to reference database: uniref90\_201901b\_full.dmnd aligning to reference database: uniref90\_201901b\_ec\_filtered.dmnd total bugs after translated alignment: 0 total gene families after translated alignment: 0 unaligned reads after translated alignment: 100.0000000000 % computing gene families … computing pathways abundance and coverage …
I am unsure as to what the reason is since we ran another alignment tool on the same fastq and found microbial species though I wanted to use HUMANN to find the metabolic pathways
Thank you for your help,
Krupa

Hello, Are there any errors in the log? If not, it would be great to check the MetaPhlAn taxonomic profile to see what species are identified and what their abundances are. It might be possible these species are less then the min abundance filter in HUMAnN. If you can provide more information that would be great!
Thanks!
Lauren

In terms of the taxonomic profile from metaphlan it comes up as as unknown and then no pathways are identified. I know the fasta file has Pseudomonas Auerginosa though not sure why HUMAnN cant identify it

Hi did you find the problem? I think it is because your files are stored in Dropbox. It says was unable to download your file.

Thank you for posting the log. That makes sense in that it looks like HUMAnN does not find any species that pass the threshold abundance in the MetaPhlAn output file. Do you see any errors in your MetaPhlAn run? If not, have you run your samples through a quality control step to remove low quality reads and host contaminate sequences?
Thank you,
Lauren

I encountered the same SyntaxWarning message as Carlos. I am pretty sure that it’s due to change in Python 3.12 where it’s now required to use raw strings (r"…") for regular expressions.
For my dataset, HUMAnN did successfully find and quantify pathways despite emitting the warning.
I’m not confident, but I think it’s possible that that MinPath WriteReport function that contains the offending string isn’t even reached during a default HUMAnN run. It appears to be specific to KEGG pathways.

Thanks for the suggestion. We are usually not testing on the most recent Python release, so this is definitely possible. We will look into it.
