78d04f1seqlab: write and view pulseq MRI sequences in the browserJeremy Magland 1// Example registry. Sources come from two places:
2// - curated hand-written scripts (fid/epi/gre) with friendlier comments
3// - auto-adapted pulseq demoSeq scripts under ./pulseq/*.m, generated by
4// scripts/gen-examples.mjs (only demos that actually run on numbl)
5// Metadata (name/category/description) is looked up in CATALOG; run-time
6// labels come from generated-timings.ts. An id without a CATALOG entry is
7// skipped, so stale generated files can't leak in unlabeled.
