    0. Intro
    
    1. User Guide
    
    2. Tutorial
    
    For convenience, image files (SIF) are temporarily stored in /volatile
    
    You may use the following URIs in commands such as apptainer run to follow along interactively with the presented tutorial:
    
    1. Analysis image from container-forge:
    
    /volatile/clas12/users/dilks/share/analysis-in-containers/analysis_latest.sif
    
    2. Image for analysis-in-containers tutorial:
    
    /volatile/clas12/users/dilks/share/analysis-in-containers/analysis_in_containers_latest.sif
    
    These SIF files are provided so that you do not have to wait for apptainer pull to download and convert them.
    
    If the files have been removed from /volatile, you can pull (download) them using
    
    apptainer pull docker://codecr.jlab.org/hallb/clas12/container-forge/analysis:latest apptainer pull docker://codecr.jlab.org/hallb/clas12/tutorials/analysis-in-containers/analysis_in_containers:latest
    
    See documentation within the repository links for more info, and the most up-to-date URIs.
