-Using an <code>SIF</code> image is recommended as disk performance (from the container image) will be faster than storing each file separately on our cluster filesystems, which are set up to handle large files and parallel I/O. Using an <code>SIF</code> file instead of a sandbox image will also only use a quota file count amount of 1 instead of thousands (some images will typically contain thousands of files and directories).

 Many Linux distribution package managers require root permissions in order to use them. This implies that Apptainer version 1.0.x and the older Singularity cannot be used on compute clusters to build images as a normal user. Should such occur, [[Technical support|submit a ticket]] asking for help to create that image or use a computer with Apptainer installed where you have root permissions.
