Let’s create an interactive session on the HPC:

...

conda install bioconda::samtools
conda install bioconda::tabix
conda install bioconda::minimap2

Now repeat the process for ‘sniffles’, then install it:

...

Now we are done installing all the tools that we need for today.

Approach #2 (we are not doing this - this just for your information) - installing all tools at once (slower option!)

Prepare the following environment.yml file:

name: ONTvariants
channels:
  - conda-forge
  - defaults
  - bioconda
dependencies:
  - samtools=1.20
  - sniffles=1.0.12
  - minimap=2-2.28
  - tabix=0.2.6

Create a new environment:

...

As you have seen, we can search at anaconda.org for other tools that we might be interested to use.

Remember, if you run into compatibility issues or errors, you can always create a new conda environment for the tool of interest. NOTE: you can switch between conda environements as follows:

conda activate myenvironment1
#... do so work with it
conda deactivate
#now we can activate another environment
conda activate myenvironment2
#... do some other tasks
conda deactivate #optional to deactivate last environment to use given that when we submit a job to the HPC cluster it will be closed automatically at the completion of the last task.
