xcms on conda

[cbroeckl]

i am trying to setup on an HPC system using conda. I have tried R 4.4.1, as well as R 4.3.1, and in each case i cannot seem to get xcms to load for various reasons - usually due to some compatibility issue or another. i was wondering if there is a guide out there in the world to get one started down this path?

I am running conda 24.7.1 via miniconda3.

https://anaconda.org/bioconda/bioconductor-xcms - this site has multiple commands available for installation, which makes me think i am not the only one struggling with this.

BELOW IS CODE to install xcms, and the progress and output:

installing the bioconda-xcms:

conda create -n xcms bioconductor-xcms

This works, but this installs a version of R from before COVID!
R version 3.6.1 (2019-07-05) -- "Action of the Toes"

And i can't actually load XCMS:

library(xcms)

Hi, thanks for reporting. Can you link to the conda recipe that needs fixing ? And open an issue there as well, and cross-link the two ? I am not familiar with the update policy of BioC packages in Conda, so we might need external help. Yours, Steffen

[cbroeckl]

I will do my best to report appropriately: but here is the link to the recipe:

https://github.com/bioconda/bioconda-recipes/tree/master/recipes/bioconductor-xcms

I didn't look closely at this prior to your reply, but it appears the recipe is actually calling for R 4.0.0.

{% set version = "4.0.0" %}
{% set name = "xcms" %}
{% set bioc = "3.18" %}

[sneumann]

Not asking for R-4.0.0, but instead it wants to install xcms-4.0.0 from BioC-3.18: https://bioconductor.org/packages/3.18/bioc/html/xcms.html So indeed would be due for some refresh. I vaguely have in mind that bioconcda and bioconductor have some procedure for updating, but I don't know details. Best place would be Bioconda chat channels. I pinged Matthias Bernt in another bioconda issue. Yours, Steffen

Try to create a clean conda env

conda create --strict-channel-priority --override-channels --channel conda-forge --channel bioconda --name xcms bioconductor-xcms

This installs a R 4.x for me and library(xcms) works.

That was magical. it worked the first try. So it was pulling an older bioconda-xcms from one of the other channels? Thanks @bernt-matthias.

[bernt-matthias]

You can check which channels have been used with conda list in the other env.

Just in case, if you are working for an institution with more then 200 people you might want to avoid the default channel and switch to miniforge. See https://www.fz-juelich.de/en/rse/the_latest/the-anaconda-is-squeezing-us

Hi, I implemented a xcms-based HPC worklfow that does parallel peak picking and parallel integration of missing values. The latter is to optimize memory usage at the heavy price of saving everything to the drive. Been tested up to 20k untargeted LCMS samples. Check it out: https://johanlassen.github.io/cXCMS/articles/HPC_workflow.html

[cbroeckl]

thanks @JohanLassen - i will certainly take a look at this and learn from it!

[jorainer]

just a quick heads up for current development we're doing: we're also working on a xcms result object that stores all data in a HDF5 file - this will reduce the amount of required memory (at the cost of more I/O) and is tailored for very large scale experiments.
