Apptainer

Definition
AI-generated

Apptainer is the open-source container runtime that succeeded Singularity under the Linux Foundation umbrella; it emphasizes secure, unprivileged execution on multi-user HPC systems and remains compatible with the same image workflows many genomics groups adopted under the earlier name.

Why it matters in GWAS

Training workshops, core facilities, and consortium pipelines often standardize on Apptainer on clusters where Docker is disallowed; publication checklists sometimes require an Apptainer definition file alongside conda lockfiles for full reruns.

Example usage

"The workflow README documents apptainer build from the published definition and bind-mounts for the VCF staging area."

Related-term network

Click any node to open that term page.

Node order. The current term is first. Next come every page linked from Related terms, in the same top-to-bottom order as that list. Then new terms appear in two-hop layers: for each of those direct neighbors (in that same order), their related terms are appended if not already listed. A third pass does the same for two-hop nodes. The walk stops when a fixed maximum number of nodes is reached.
