I'd like to be able to create chains of fungal cells and bacteria procedurally in houdini.

Please find attached a proof of concept apprentice H12.5 file.

I created a curve, then manually created groups for each group of 3 consecutive points.
Each of these are then used as copy sops for meta balls.
Which are then converted to polygons and merged.

I"d like to automate as much of the able as possible.

e.g. automatically creating groups from every group of N points on the curve.
Then converting those groups into metaballs, etc.

Any suggestions would be much appreciated.

thanks

Sorry, didn't look at your file but have you tried using a Partition SOP? Something with the rule:
group`floor($PT/N)` (where N is the number of points in the group)
