Subject: Issue with GenomeInfoDb
Greetings,
I provide support for an HPC cluster at the University of Michigan. Recently we
had a user approach us with the following problem:
I have an issue about using the following package/function in R.
*library("GenomeInfoDb")*
*GenomeInfoDb::Seqinfo(genome = "mm10")*
The function is getting a remote resource that works on the head node, but
not the worker nodes. The error on worker nodes is as follows.
*Error in .make_assembly_report_URL(assembly_accession)*
We have our cluster setup to use proxy variables to be able to access the
internet from our compute nodes. After some digging, my colleague, Mark
Montague, was able to come up with the following work around:
This is not a security issue. The problem is that our cluster compute nodes are
not connected to the Internet.
Because of this, compute nodes need to use a proxy server in order to access
things that are off campus. Usually this
is not a problem, but in this particular case there are actually three problems
related to GenomeInfoDb not working
correctly with the proxy when running on compute nodes:
1. GenomeInfoDb doesn't recognize the FTP directory listing format our proxy
server uses.
2. GenomeInfoDb is not handing the download of assembly reports in the same way
it handles other downloads, which is a
problem when the proxy is being used.
3. R is not always using the proxy for FTP connections; this appears to be a
quirk of R.
To fix problems 1 and 2, you can install a modified version of GenomeInfoDb to
replace the one you currently have
installed in your home directory by running the following commands:
cd ~
git clone https://github.com/Bioconductor-mirror/GenomeInfoDb.git
cd GenomeInfoDb
git checkout release-3.4
patch -p 1 < /home/someuser/GenomeInfoDb.patch
R CMD INSTALL .
To fix problem 3, you need to tell R to use libcurl to download files rather
than its default method. This needs to be
done in every R script that uses GenomeInfoDb. For example:
options(download.file.method="libcurl")
library("GenomeInfoDb")
GenomeInfoDb::Seqinfo(genome = "mm10")
Alternatively, you can put the "options" command above into a file named
/home/someuser/.Rprofile and it will take effect
for all R scripts you run.
Just thought you would like to know.
Cheers,
Ken
