heat to tail

I know I can use Link Node to match C1CCCCC1, just curious why I cannot use "ht" repeating group to specify the query as shown in the attachment?

Hi Yingyao,





The searching of this feature is being implemented, and will appear soon with JChem 5.2.





Actually, it will support flexible repetition ranges like 2-3,5,7








Best regards,
