Hi, Everybody!
Does anyone out there have a technique for getting the variance out of
a profile object? A profile object is good at getting <X> vs. B, I'd
then like to get < (X - <X>)^2 > vs B. Matt and I had spittballed the
possibility some time ago, but I was wondering if anyone out there had
successfully done it.
Thanks,
d.

Hi yt gurus,
I've been making projections of star_density from enzo output files
and they seem to be working out fine. However, wherever particles do not
exist the background remains white instead of following my chosen colormap.
Is there a way to paint these areas to follow the colormap?
thanks!
Munier
I've attached an image of what gets plotted, and the relevant bits of my
script are:
*from yt.mods import **
*
*
*fName = "DD0006/test_sim_0006"*
*var = "star_density"*
*axis = 0*
*
*
*pf = load(fName)*
*pf.h*
*
*
*pc = PlotCollection(pf)*
*p = pc.add_projection(var,axis)*
*#p.modify["particles"](1.0)*
*
*
*radius = .02;*
*
*
*pc.set_xlim(.5-radius,.5+radius)*
*pc.set_ylim(.5-radius,.5+radius)*
*
*
*pc.save(fName)*

Is this behavior familiar to anyone? I've done this with a fresh
build and one from a few months ago.
The set was generated with the latest build of enzo. With a set
generated from an earlier enzo build, I can read the set just fine.
Thanks!

Hey all,
I've been trying to stick yt on an opensuse box, and I've run into a kind of funky error when it attempts to install mercurial-2.2.2. I just wanted to see if perhaps anyone has hit this wall before?
user_base = getuserbase() # this will also set USER_BASE
File "/home/nearl/yt-x86_64/lib/python2.7/site.py", line 243, in getuserbase

raise IOError(msg)
IOError: invalid Python installation: unable to open /home/nearl/yt-x86_64/lib/python2.7/config/Makefile (No such file or directory)
The directory /config does not exist. I've attempted to install the python-devel package, along with the python-setuptools-devel package, but they didn't seem to help at all.
I haven't worked with opensuse before, so it's quite possible that this may be a platform-dependent issue. Any suggestions would be greatly appreciated!

Hi,
I gather that cylindrical geometries aren't supported. Is it possible to force yt to read in cylindrical coordinates as though they were cartesian?
When I try to load an athena vtk in cylindrical, I get:
In [32]: pf = load("cyl_disk.0001.vtk")
yt : [INFO ] 2012-11-15 15:31:26,443 Temporarily setting domain_right_edge = -domain_left_edge. This will be corrected automatically if it is not the case.

yt : [INFO ] 2012-11-15 15:31:26,445 Parameters: domain_dimensions = [ -37 128 -2147483648]

yt : [INFO ] 2012-11-15 15:31:26,445 Parameters: cosmological_simulation = 0.0
This is a 256 by 128 grid, and the dimensions should be -pi/2, pi/2 and 1, 15.
Thanks,

Hey all!
When I try to call my own added field magB I get a runtime error saying
that the cgs unitsystem is
unrecognized. When I insert pf["unitsystem"] == "cgs" directly before
the call where the traceback
starts, it returns true.
Best wishes,
Patrick
I add the field with:
def _magB(field,data):
return (na.sqrt(data["Bx"]**2 + data["By"]**2 + data["Bz"]**2))
add_field("magB", function=_magB, units=r"\rm{Gauss}")
and then call:
rad_profile.add_fields("magB")

Hey all,
So I still get some strange behaviour with the ProjectionPlot. If I use
the projection.set_width() with the clumps callback method I get the
real image shrinked inside the the plot window. Strange thing is, that
it grows with each step! Here is a demonstration how it looks (you have
to look closely as it doesn't grow that much each step):
http://www.flickr.com/photos/87912862@N05/sets/72157631990474435/
If I don't use the set_width() then the image itself looks fine, but the
scale on the axis grows with each step. So it seems to be the same error
than with fixed width.
Best wishes,
Patrick
Here is the code that I am using:
# ID is just a list of tuples with clumps/their position in an array
# sim_files and clump_files is a list containing the filenames
# get_myclump() simply returns a specific clump
for j, series in enumerate(ID):
for i in series:
pf = load(sim_files[i[0]])
myclump = get_myclump(clump_files[i[0]], i[1])
pc = ProjectionPlot(pf, axis, my_field, center =
pf.domain_center, weight_field = my_wfield)
pc.set_width(28, "mpc")
pc.annotate_text([0.0,1.05], "Clump %s" % j)
if redshift:
pc.annotate_text([0.917,1.05], "z = %0.4f" %
pf.current_redshift)
if grid:
pc.annotate_grids()
if fix_scale:
pc.set_zlim(my_field,boundaries[0],boundaries[1])
pc.set_cmap("Density", "idl01")
pc.annotate_clumps(myclump)
pc.save('%s/Clump_%s_File_%s_Nr_%s_%s_Projection.png' %

Hi all,
