[BioC] TxDb file for Drerio (ie zebrafish)

[Brodsky, Michael]

Hi. I am an investigator at the University of Massachusetts Medical School. I've been using the CRISPRseek package written by my colleague Julie Zhu and I'd like to perform searches on the zebrafish genome, but am unable to find a TxDb file for this widely studied organism. Is there a mechanism to request that a TxDb file be prepared for Drerio?

Thank you,

Mike Brodsky
