Hi everyone
I am trying to port my 16S workflow that uses dada2, phyloseq and DECIPHER onto a Linux server. I have split the jobs up and am using snakemake to run through them. Seems fine.
When I go onto the server, I use conda to create a new environment and then install snakemake and R v4.0.3 into it.
# first install mamba as its faster for installing than conda
conda install -c conda-forge mamba
# create an environment
mamba create -n dada2_pipeline
# open the environment
conda activate dada2_pipeline
# install needed dependencies for the pipeline
mamba install -c bioconda -c conda-forge snakemake=6.0.5
mamba install -c bioconda fasttree
mamba install -c conda-forge r-base=4.0.3
I then planned on going into R to install the necessary dependencies, but Rsamtools fails, see here, but what more curious is when I try and install bioconductor packages using conda, they regularly ask me to downgrade my R to install them, which of course I do not want to do.
mamba install -c bioconda bioconductor-rsamtools=2.6.0
Wants me to downgrade my R (which is 4.0.3) to 3.3.1. And also gives me the issue Problem: nothing provides icu 54.* needed by r-base-3.3.1-1.
Just wondering how best to set up an environment with a standalone version of R and to install all the necessary packages from Bioconductor.
