Is the input format correct?
- an item cannot appear more than once per transaction
- items are sorted on each line
- items are positive numbers
That could be the problkem

Hi, I see.
You can send me your dataset to philfv8 AT yahoo DOT com
and tell me what is the minimum support value,
and I can test it to see what is the problem.
If there was a bug, I guess it would be in the NegFin algorithm, since other algorithms like FPGrowth have been quite extensively tested and used by many people but we never know. I can check to find out what is the problem.
Best regards,
Philippe
