Performance

bids-matlab’s performance may vary depending on which options you choose for indexing with bids.layout().

Relying on the BIDS schema ('use_schema', true) to only include files that comply with it may slow down performance a bit.

Index dependencies ('index_dependencies', true) to detect files with explicit dependencies between them (for example when a fieldmap mentions that is intended for a specific bold run) is much slower and you may consider setting this to false when if you know that you have no such dependencies in your dataset.
