I am trying to donwload the microbial genome using the repophlan_get_microbes.py (https://github.com/SegataLab/repophlan) but now it is running more than 10 days and still not finished on slurm HPC.

Could anyone please suggest what is the issue with the script?

UPDATE 2: new log posted

take-home message: I think it is working, it's just that a few errors happen sometimes when downloading things from big databases.

It looks like there are a few warnings or errors associated with getting specific files. I think this is actually ok. For example for one of the genomes, I logged into the ftp manually to check if the file was there:

So in this particular case, that genome exists but is just missing a faa.gz file. So the script appears to be working as expected, it's just that some of the NCBI submissions don't have everything they are supposed to have.

(As a tangent, that Rumen genome came from a paper I'm an author on I'm pretty sure!! So I guess you could blame me for the missing file if you wanted, though I was in no way involved with annotations or submission...)

UPDATE: now the log is posted

It does not look like a connectivity issue based on the new information provided in the first and last lines of the log file. There it looks like there are a lot of processes finishing quickly towards the beginning and the end of the process (e.g. 48 hours apart).

Based on this new information, I am wondering if you have simply managed to get a taxonomy file that is much larger (e.g. >10X larger to explain the time difference) than anticipated when the README for the script was written, and thus it simply takes a long time.

It would still probably be best to go through the log file rather carefully and see if there is a big hang in the process, errors, warnings, etc.

Here is what they say in the repo:

*** Download the microbial (bacteria+archaea) genomes (fna,ffn,faa,frn) with 
    corresponding taxonomy
$ ./repophlan_get_microbes.py --taxonomy taxonomy_reduced.txt --out_dir /
  microbes --nproc 20 --out_summary repophlan_microbes.txt /
  | tee repophlan_microbes.log
[ ~6 hours ]. Downloads and save all available sequences for microbes. It uses
multiple parallel connections to speed up the retrieval: common exceptions 
including issues with the NCBI ftp which temporarily rejects connections for
ftp load problems are handled gracefully with a 'delay and retry' policy. 
IMPORTANT: specifying more than 20 processors to run in parallel causes serious
problems in terms of exceeding the allowed number of connections by NCBI causing
long delays.

Since your script is taking much much longer than 6 hours, it probably didn't work.

Some thoughts based only on the info in the repo:

  • "IMPORTANT: specifying more than 20 processors to run in parallel causes serious problems in terms of exceeding the allowed number of connections by NCBI causing long delays." this sounds like your problem. I think you are asking for 60 nodes ("tasks"? "nodes" is 3 which should be ok). Drop tasks to 20 or less and see what happens, maybe.
  • "...temporarily rejects connections for ftp load problems are handled gracefully with a 'delay and retry' policy." It is possible that there is a bad request in there that it keeps trying over and over again unsuccessfully, it could keep going forever if such a problem exists and you don't stop it.

As pointed out in the comments, you should check the log and post that here.

As also pointed out in the comments, you might consider posting an issue at the repo as they are more familiar than we are.

Other things to check:

  • how much disk space do your nodes have access to? is it enough for the download?
  • are you satisfying all dependencies of the script? In other words do you need to load more modules?

  • $\begingroup$ Thanks for your time and help. Actually we don't have active FTP connection on server which is required for the download. That can be a issue? $\endgroup$ – bioinfonext Sep 19 at 6:37
  • $\begingroup$ @bioinfonext Yes, that probably explains it. This would fall under the second bullet point of my answer: it keeps on trying to use an FTP connection which your server doesn't support, which fails, and then it waits and retries, which fails, and then it waits and retries... which would explain the long run-time as noted in the answer and their documentation. $\endgroup$ – Maximilian Press Sep 19 at 19:30
