Hi devs,

I'm running mob v. 3.1.0 . When I run mob_recon, it seems to complete successfully with the following message.

2023-02-14 00:24:27,762 mob_suite.mob_recon INFO: MOB-recon completed and results written to /well/aanensen/projects/amr-landscape/mob-recon/klebsiella_pneumoniae/results/SRR6656623 [in /apps/eb/testing/skylake/software/MOB-suite/3.1.0-foss-2019b-Python-3.7.4/lib/python3.7/site-packages/mob_suite/mob_recon.py:1445]

However, when I look at the log I see the following ERROR and WARNING messages:

2023-02-14 00:23:26,440 root ERROR: blastn on db /well/aanensen/projects/amr-landscape/mob-recon/klebsiella_pneumoniae/results/SRR6656623/__tmp/fixed.input.fasta and query /well/aanensen/shared/software/mob_database/2023-02-09/repetitive.dna.fas STDERR: b'BLAST Database error: No alias or index file found for nucleotide database [/well/aanensen/shared/software/mob_database/2023-02-09/repetitive.dna.fas] in search path [/gpfs3/well/aanensen/projects/amr-landscape/mob-recon/klebsiella_pneumoniae/scripts::]\n' [in /apps/eb/testing/skylake/software/MOB-suite/3.1.0-foss-2019b-Python-3.7.4/lib/python3.7/site-packages/mob_suite/blast/__init__.py:160]

Could you help me understand this error, and whether it may have an effect on the results?

All the best

Hello, this issue is resolved in v. 3.1.4, please update to that and try again.

Thanks for the response @jrober84 . I'll try that. In the meantime, does this problem alter the results? Asking because it may take a me a bit to get the newer version installed.

The missing repetitive element "error" is pointing to an incorrectly setup database. It can affect the results since it would mask contigs that are just IS/TE etc from forming plasmids by themselves. So I would recommend first trying mob_init again and making sure that the blast database for /well/aanensen/shared/software/mob_database/2023-02-09/repetitive.dna.fas is constructed. Or you can call makeblastdb on the file directly makeblastdb -in /well/aanensen/shared/software/mob_database/2023-02-09/repetitive.dna.fas -dbtype nucl to make sure it is initialized.
