Hi Vikram,
Thank you for contacting us. You are correct; the Pfam track is not
available on hg18. However, one of our engineers is looking into it and
may be able to generate this track for you. We'll let you know in a day
or so.
If you have further questions or comments, please reply to
gen...@soe.ucsc.edu.
Regards,
