st: qcount convergence

Dear Statalist,
I am using qcount, a command that estimates quantile regression for discrete data (the command is based on quantile regression models for count data using the jittering method
suggested by Machando and Santos Silva (2005), Quantiles for Counts, Journal of the American Statistical Association 100, 1226-1237.
The idea is to add a random variable to the discrete outcome to smooth the distribution.
I have a problem with the replications. In some estimations for at least one replication no convergence can be reached. I know that for the bootstrap command there exists a subcommand that solve the problem by excluding replications that do not converge. Is there also a solution for the qcount command?
Thanks,
Barbara
