Hi Matt and Jeff, Thanks for the suggestions! I'll look into the FLASH reader and get back to you if I have any question. I'm eagerly looking forward to using yt!

First off -- *please* feel free to ask questions. We're an eager-to-help bunch, and I'd like to make sure that the GAMER format addition goes without too much difficulty for you! You can also feel free to stop by in IRC ( #yt on chat.freenode.org ) where a couple people are usually available. I would actually recommend starting with a different method -- the simplest reader is probably FLASH, which is very straightforward (and as you note, similar to the GAMER format.) The "how to add a frontend" should be mostly up to date, but I went ahead and put into the yt/frontends/_skeleton directory the skeleton of a frontend, with comments, drawn from the FLASH frontend. (This is why it took me a bit to write back.) Basically what you need to do: 1) Create a yt/frontends/gamer/ directory, and copy over everything except __config__.py from the _skeleton directory 2) Rename all the items in the data_structures and fields.py to be GAMER instead of Skeleton 3) Implement the routines necessary inside the various classes and .py files I hope that helps, but please do write back if you run into trouble -- and if you'd like to share a dataset and have one of us write the frontend, that would also work!
