I have created a conda install of the workflow using the following commands:
conda create -n env_name -c bioconda python=3.7
conda activate env_name
conda install -c biobakery biobakery_workflows
pip install leveldb
I try to run the wmgx workflow on demo data using the follow (each flag seems to be required for my install of the workflow to attempt a run):
biobakery_workflows wmgx --input fastq/ --output demo_out/ --bypass-strain-profiling --local-jobs 6 --threads 2 --qc-options="--trimmomatic=/data/Microbiome/RefData/Metagenomics/biobakery_workflows_databases/Trimmomatic-0.39/" --functional-profiling-options="--nucleotide-database /data/Microbiome/RefData/Metagenomics/biobakery_workflows_databases/humann/humann_database/chocophlan/ --protein-database /data/Microbiome/RefData/Metagenomics/biobakery_workflows_databases/humann/uni_db/uniref"
I get the following error:

Based on this post I found online, I had a server administrator sudo install the TBB library, but this did not solve the issue. I then tried to uninstall the bowtie2 that came with the workflow/kneaddata (conda remove bowtie2), but I would have to delete all the workflow software for conda to successfully remove bowtie2.
I decided to try to manually delete bowtie2 from my conda directories by deleting the executable from ./conda/pkgs/bowtie2* then reinstall bowtie2 with conda, but this also did not solve the problem.
I’m not sure else how I can troubleshoot this problem. It seems to be an issue with the conda install of bowtie2 as part of the workflow. Note that two weeks ago, I didn’t have this problem, but since trying to recreate the conda env. using the steps above, this problem has arisen. Was there by chance a new update in that time?
