Hi all,

My humann is v4.0 and metaphlan is version 4.1.0 (23 Aug 2023).  
I downloaded the databases using the following link because I still couldn’t use `humann_databases --download` :  
[HUMAnN database download - Microbial community profiling / HUMAnN - The bioBakery help forum](https://forum.biobakery.org/t/humann-database-download/6690)

And then updated config file as below:

```auto
HUMAnN Configuration ( Section : Name = Value )
database_folders : nucleotide = /ibers/ernie/home/yil23/chocophlan/
database_folders : protein = /ibers/ernie/home/yil23/uniref/
database_folders : utility_mapping = /ibers/ernie/home/yil23/metacyc/
run_modes : resume = False
run_modes : verbose = False
run_modes : bypass_prescreen = False
run_modes : bypass_nucleotide_index = False
run_modes : bypass_nucleotide_search = False
run_modes : bypass_translated_search = False
run_modes : threads = 1
alignment_settings : evalue_threshold = 1.0
alignment_settings : prescreen_threshold = 0.5
alignment_settings : average_read_length = 150
alignment_settings : translated_subject_coverage_threshold = 50.0
alignment_settings : translated_query_coverage_threshold = 90.0
alignment_settings : nucleotide_subject_coverage_threshold = 50.0
alignment_settings : nucleotide_query_coverage_threshold = 90.0
output_format : output_max_decimals = 10
output_format : remove_stratified_output = False
output_format : remove_column_description_output = False

```

And I ran humann and got this error:  
CRITICAL ERROR: The directory provided for ChocoPhlAn contains files ( alaS.centroids.v201901\_v31.ffn.gz ) that are not of the expected version. Please install the latest version of the database: SGB

I check multiple times that I am using the latest version.  
If someone can help me this issue. That will be really helpful.  
Thank you.

Did you pull the HUMAnN 4 source code from the development branch? We haven’t formally released that version yet, so the corresponding databases are not currently provided for download (hence the error message).

Hi Franzosa,

Thank you for replying. I already changed my version to v3.9 and fixed this issue. Thank you for your help.
