Could we try to unify with this code @chrishalcrow ?

Add SLAy as a method for
compute_merge_unit_groupshttps://www.biorxiv.org/content/10.1101/2025.06.20.660590v1SLAy combines a template similarity measure, a cross-correlation significance measure and a sliding refractory period violation measure to make a merge decision. You need an analyzer with templates, correlograms and template_similarity. If you do, you can try it using:
or, for more control, e.g.
This is an approximate implementation. Some details
_sliding_RP_violand_compute_xcorrfunctions from https://github.com/saikoukunt/SLAy . I think the sliding RP computation is fairly different between our implementation in quality_metrics. Will take a closer look...To do:
