EPS figures in matplotlib (*slightly* off topic)
by John ZuHone Feb. 12, 2012

Feb. 12, 2012

Hi all, Firstly, I recognize I should probably send this to a matplotlib list so I will do that also. However, I figure this is not a bad place to ask. I'm using matplotlib to write EPS figures, just simply using fig.savefig("test.eps"). However, I'm getting banding effects in the colorbar that I'm not seeing with other formats. I've attached an example. Any suggestions? Best, John Z

FLASH hydro parameters?
by Nathan Goldbaum Feb. 12, 2012

Feb. 12, 2012

Hi all, I just noticed that hydro parameters like Gamma and EOSType are not defined for flash parameter files. This makes it impossible to compute the sound speed using the definition in universal_fields.py. I've already modified the FLASH reader to ignore EOSType but I can't figure out how to gracefully figure out what Gamma is. It looks like enzo somehow automatically detects the existence of the Gamma parameter, but I don't see how the enzo reader does this. Can someone point me to the … [View More]

error extracting 2d phase info with user defined field
by Christine Simpson Feb. 10, 2012

Feb. 10, 2012

Hi all, I'm having trouble with the script pasted here: http://paste.yt-project.org/show/2159/ I am trying to extract a 2d phase profile with a user defined field. I can make the phase plot in a plot collection with this field by using add_phase_sphere, but I want to write the data to a file and I am getting an error with BinnedProfile2D. The error is pasted with the script. It seems that yt accesses all the fields needed to compute the field, but the field is empty somehow? I'm kind of … [View More]

Hi, I'm trying to install readline to work with iyt via: yt/bin/pip install readline But gcc can't find the libncurses library: gcc -pthread -shared -L/home/taskere/yt/lib/ -L/home/taskere/yt/lib64/ -L/home/taskere/yt/lib/ -L/home/taskere/yt/lib64/ -L/home/taskere/yt/lib/ -L/home/taskere/yt/lib64/ -L/home/taskere/yt/lib/ -L/home/taskere/yt/lib64/ build/temp.linux-x86_64-2.7/Modules/2.x/readline.o readline/libreadline.a readline/libhistory.a -lncurses -o build/lib.linux-x86_64-2.7/readline.… [View More]

Obtaining projection data value
by Jun-Hwan Choi Feb. 8, 2012

Feb. 8, 2012

Hi all, I wonder whether that I can obtain the value that generate projection plot. I can make a projection image for my disk using add_projection in the plot_collation. I am interested in to get the projected density value and its position (and its pixel size) to perform the FFT analysis in order to find the non-axisymmertic feature such as disk-bar. Is there way to get this values using yt? Thank you in advance, Junhwan -- -------------------------------------------------------------- … [View More]

YT analysis questions: cylindrical profile and RMS velocity
by Jun-Hwan Choi Feb. 6, 2012

Feb. 6, 2012

Hi YT users, I have two questions on the YT analysis: First, I would like to make profiles (mass, angular momentum) in the cylindrical coordinate. In other world, the profiles depend on r_xy (x-y is the cylinder plane). I define disk object and compute Profile as follow: > disk = pf.h.disk(center, [0, 0, -1], (100., 'pc'), (1., 'pc')) > profile = BinnedProfile1D(disk, 50, 'Radius', smallest_bin, largest_bin, lazy_reader=True) ,but I find that Radius is for x,y, and z distance. Can I get … [View More]

Install yt on Eureka.alcf.anl.gov
by Min Long Feb. 6, 2012

Feb. 6, 2012

Dear yter, Is there anyone who once successfully installed "stable" version of yt on Eureka.alcf.anl.gov? I've tried: $ wget http://hg.yt-project.org/yt/raw/stable/doc/install_script.sh $ bash install_script.sh but it got stuck during the installation of Mercurial: Downloading HDF5 Downloading hdf5-1.8.7.tar.gz from yt-project.org Downloading zlib-1.2.3.tar.bz2 from yt-project.org Downloading bzip2-1.0.5.tar.gz from yt-project.org Downloading libpng-1.2.43.tar.gz from yt-project.org … [View More]

Installing on an IBM Power6
by Andrew Davis Feb. 2, 2012

Feb. 2, 2012

Hi folks, I'm working on installing yt and enzo on a new (to me) cluster, which is an IBM Power6 running AIX. It's having major issues with installing stuff, from basic things like the tar command not having a -z option, to significant issues actually compiling things. I'm still workign through things, but figured I'd ask if anyone has compiled yt and enzo on an AIX machine before? If not, I'll try to submit the final install script that works, along with details of how I've had to modify … [View More]

modify['marker']
by Elizabeth Tasker Feb. 1, 2012

Feb. 1, 2012

Hi, Would it be possible to add in the option to specify a colour for the 'marker' plot modification mechanism, like that for 'particles'? Currently, yt colours all the markers differently, but if you have a lot of the same type, it would be great to keep them the same. Elizabeth

Hi all, The yt workshop last week in Chicago ( http://yt-project.org/workshop2012/ ) was an enormous success. On behalf of the organizing and technical committees, I'd like to specifically thank the FLASH Center, particularly Don Lamb, Mila Kuntu, Carrie Eder, for their hospitality; the venue was outstanding and their hospitality touching. Additionally, we're very grateful to the Adler Planetarium's Doug Roberts and Mark SubbaRao for hosting us on Wednesday evening -- seeing the planetarium … [View More]
