loading halo off disk problem
Hi Stephen, I was trying your two examples shown on "Loading Haloes Off Disk" in the documentation, I can do to both: haloes[0].center_of_mass() to find the center of mass coordinate xyz of the 0th halo, but when I tried to get the particle positions by doing haloes[0]["partilcle_position_x"] I succeeded with the first method while the data is still in memory, but fail in the second method when it is loaded off disk, can you verify this? It'll save a lot of time if I have the particle positions without having to run the profiler every time. error pasted at: http://paste.enzotools.org/show/NyLEwvGzl2RGBOcAcfKH From G.S.
Hi Geoffrey,

This is a HDF5 error. Did you do the halo finding in serial? If so, there should be only one h5 file you saved, and you can do something like this: % h5ls HopAnalysis.h5 | grep Halo00000000 and tell me if you see Halo00000000 Group If you don't see that, that will tell me something. If you do, then something else is going on. Let me know! -- Stephen Skory s@skory.us http://stephenskory.com/ 510.621.3687 (google voice)
gso:64_SN_nometal gso$ h5ls halo_list.h5 | grep Halo00000000 Halo00000000 Group And yes I ran the parallelHOP in serial. Do I have to run it in parallel? Or is my HDF5 broken? From G.S.

Geoffrey, Can you tar up that data die and put it on Triton for me? That will help tremendously. Then I can take a look for you. Sent from my Pocket Genius On Apr 11, 2011, at 4:13 PM, gso@physics.ucsd.edu wrote:
