Is pc.add_projection("Density", ax) a valid statement ?
Hi, In the following code, I am getting an error when I use pc.add_projection("Density", ax). But If I specifically use pc.add_projection("Density", 0) then it runs fine. Any idea ?
Code...
from yt.mods import * pf = load("RedshiftOutput0002") pc = PlotCollection(pf) for ax in range(3): p = pc.add_projection("Density", ax) p.modify["hop_circles"](halos, max_number=None, annotate=True, min_size=0, max_size=100000000, font_size=8, print_halo_size=True, print_halo_mass=True, width=None) pc.save()
Error....
Traceback (most recent call last): File "hop_yt.py", line 20, in <module> p = pc.add_projection("Density", ax) File "/autohome/u118/agarwa23/enzo1/src/yt/yt/raven/PlotCollection.py", line 262, in add_projection return self._add_projection(PlotTypes.ProjectionPlot, *args, **kwargs) File "/autohome/u118/agarwa23/enzo1/src/yt/yt/raven/PlotCollection.py", line 285, in _add_projection center=center, **kwargs)

Hi Shankar,
The code looks okay to me. Can you please send the whole error message or run with --paste so that we can see what is going wrong? The traceback seems truncated.
Does it work without the hop circles?

Hi Shankar,
I'm afraid this error is new to me. The projection unable to find a field generated by the projection itself, which I've never seen before. The code you pasted works for me.
There are two things I can think of to try:
1. delete any *.yt files you can find in the directory 2. change "pc.save(fn)" to "pc.save()"
Other than that, I'm afraid I'm at a loss. Changing "0" to "ax" should not have this impact... Sorry!

Hey Matt, Never mind. I can live with that. By the way, here is the first few lines from HopAnalysis.out
# HALOS FOUND WITH HOP # Group Mass # part max densx y z center-of-mass x y z vx vy vz max_r 0 1.009603589e+15 3202 6.803410660e+03 2.691574395e-01 1.892197430e-01 8.293117285e-01 2.701045173e-01 1.889703433e-01 8.276973165e-01 -6.232934392e+06 -2.872425257e+07 1.526929994e+06 1.886896417e-02
Here, vx=-6.232934392e+06 vy=-2.872425257e+07 vz= 1.526929994e+06
http://yt.enzotools.org/doc/extensions/running_halofinder.html says that "the velocity of the center of mass of the halo is in simulation units."
And I found this in the RedshiftOutput0002 file...
DataLabel[3] = x-velocity DataUnits[3] = none #DataCGSConversionFactor[3] = 5.70277e+09 DataLabel[4] = y-velocity DataUnits[4] = none #DataCGSConversionFactor[4] = 5.70277e+09 DataLabel[5] = z-velocity DataUnits[5] = none #DataCGSConversionFactor[5] = 5.70277e+09
The factor of 5.70277e+09 when MULTIPLIED with the simulation velocities is supposed to convert them into cm/sec. I have checked this to be correct against the particle-velocity dump by Enzo.
But the Hop velocities above are weird. I have no idea how to incorporate 5.70277e+09 with vx,vy,vz above.
I tried... print lagos.fieldInfo["velocity"].units but got... KeyError: 'velocity'

Here, vx=-6.232934392e+06 vy=-2.872425257e+07 vz= 1.526929994e+06
http://yt.enzotools.org/doc/extensions/running_halofinder.html says that "the velocity of the center of mass of the halo is in simulation units."
And I found this in the RedshiftOutput0002 file...
DataLabel[3] = x-velocity DataUnits[3] = none #DataCGSConversionFactor[3] = 5.70277e+09 DataLabel[4] = y-velocity DataUnits[4] = none #DataCGSConversionFactor[4] = 5.70277e+09 DataLabel[5] = z-velocity DataUnits[5] = none #DataCGSConversionFactor[5] = 5.70277e+09
The factor of 5.70277e+09 when MULTIPLIED with the simulation velocities is supposed to convert them into cm/sec. I have checked this to be correct against the particle-velocity dump by Enzo.
But the Hop velocities above are weird. I have no idea how to incorporate 5.70277e+09 with vx,vy,vz above.
I tried... print lagos.fieldInfo["velocity"].units but got... KeyError: 'velocity'

Hi Shankar,
I'm afraid this error is new to me. The projection unable to find a field generated by the projection itself, which I've never seen before. The code you pasted works for me.
There are two things I can think of to try:
- delete any *.yt files you can find in the directory
- change "pc.save(fn)" to "pc.save()"
Other than that, I'm afraid I'm at a loss. Changing "0" to "ax" should not have this impact... Sorry!

Hi Shankar,
The code looks okay to me. Can you please send the whole error message or run with --paste so that we can see what is going wrong? The traceback seems truncated.
Does it work without the hop circles?
