Plotting a Gadget File #4

Open markushaider opened 11 years ago

Hi, I am trying to plot the dark matter distribution in a Gadget file and tried to follow the tutorial in the wiki. When I do use('/home/markus/Desktop/dmevo/100mpc/snapshot_000','massiveblack')

I get the following error:

In [12]: use('/home/markus/Desktop/dmevo/100mpc/snapshot_000','massiveblack')

ValueError Traceback (most recent call last) /home/markus/ in () ----> 1 use('/home/markus/Desktop/dmevo/100mpc/snapshot_000','massiveblack')

/home/markus/ in use(snapname, format, periodic, origin, boxsize, mapfile, **kwargs)

/usr/local/lib/python2.7/dist-packages/gaepsi/store.pyc in use(self, snapname, format, periodic, origin, boxsize, mapfile, _kwargs) 139 """ 140 self.snapname = snapname --> 141 self._format = Reader(format, _kwargs) 142 143 try:

/usr/local/lib/python2.7/dist-packages/gaepsi/readers/init.pyc in Reader(reader, kwargs) 24 classname = 'Snapshot' 25 except Exception as e: ---> 26 modulename, classname = reader.rsplit('.', 1) 27 module = import**('gaepsi.readers.%s' % modulename, globals(), {}, [classname], 0) 28

ValueError: need more than 1 value to unpack

So I am not sure what the problem is. Is it that massiveblack is the wrong file format? I think I use gadget format 1, to what would this correspond?

please pull in get the most recent git head and use 'cmugadget' as the format.

I've made a few changes regarding input file formats recently, made them a lot smarter (it will now deal with single/double precision and 8byte/4byte ids automatically), but haven't update the documents. I also added an example in examples/ directory.

Thanks
