Error running panphlan_map

[sanpande]

Hi, Is the tool still being maintained? I get the following error, any idea what is causing it?

Thank you sp

Hello,

thanks for using PanPhlAn and reporting this issue, it helps improving the software. The problem here seems to be in reading the samtools mpileup results that are by default written in a tmp file. If your execution of panphlan_map.py has been interrupted, then the file might still be present (not erased at the end of the run). Can you check the content of your /tmp/panphlan_w96kyqix.csv ? Looking at it might help a lot to solve the problem.

Otherwise it can also come from the samtools version (I use the 1.10 where you used the 1.7), but actually I would be surprised it this is causing the issue.

Best regards, Léonard

I see the file. looks like the last row is not complete.

Hello,

I updated PanPhlAn to version 3.1 and fixed the bioconda recipe that shoul solve problem of boztie2 and samtools version

Hello Léonard,

Is there potentially an issue with bowtie2 and samtools version needed? I have not found a similar issue reported, this one posted here seems the closest to my issue.

I installed using conda install -c bioconda panphlan This installed bowtie2 2.4.1 , samtools 1.9 and panphlan 3.1 in my panphlan conda environment.

When I run panphlan_map.py, I get the following error, which I'm wondering if is due to the bowtie2 version installed?

STEP 1. Checking software... /home/user/.conda/envs/panphlan_test/bin/bowtie2-align-s: symbol lookup error: /home/user/.conda/envs/panphlan_test/bin/bowtie2-align-s: undefined symbol: _ZN3tbb10interface78internal15task_arena_base19internal_initializeEv (ERR): Description of arguments failed!

Thanks, Brent

Hi,

Indeed the bowtie2 installation seem to have some issue. It seems that a similar issue occurred here: https://forum.biobakery.org/t/unknown-bowtie2-errors/1871

Tell me if you manage to fix it

Thank you for sharing. Downgrading tbb worked using: conda install tbb=2020.2
